Subject	[Csnd] tablei gives "nan" at last index
	hi - i see a littlebit strange behaviour of tablei. if it reads this function table ... giFt1 ftgen 1, 0, -10, -2, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.10 ... it says that index 9 is not a number. if i add an extra argument (which should actually be senseless), it's ok. is this a bug? or is it related to the size of the table (not a power of two - size=8 seems to be ok)? it works if i put the f-statement in the score, and tab_i instead of tablei works, too. joachim giFt1 ftgen 1, 0, -10, -2, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.10; "nan" giFt2 ftgen 2, 0, -10, -2, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.10, 0; ok instr 1 prints "%nFunction Table %d:%n", p4 indx init 0 loop: ival tablei indx, p4 prints "Index %d = %f%n", indx, ival loop_lt indx, 1, ftlen(p4), loop endin i 1 0 0 1 i 1 0 0 2 output: Function Table 1: Index 0 = 1.000000 Index 1 = 2.000000 Index 2 = 3.000000 Index 3 = 4.000000 Index 4 = 5.000000 Index 5 = 6.000000 Index 6 = 7.000000 Index 7 = 8.000000 Index 8 = 9.000000 Index 9 = nan Function Table 2: Index 0 = 1.000000 Index 1 = 2.000000 Index 2 = 3.000000 Index 3 = 4.000000 Index 4 = 5.000000 Index 5 = 6.000000 Index 6 = 7.000000 Index 7 = 8.000000 Index 8 = 9.000000 Index 9 = 10.100000 Send bugs reports to the Sourceforge bug tracker https://sourceforge.net/tracker/?group_id=81968&atid=564599 Discussions of bugs and features can be posted here To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound"

	as to the power-of-two question i am really not sure. obviously the table opcode work also for non-power-of-two tables, and i can't find anything in the manual against it. if it's easy for you to have a look in the code and see if it's really no difference in the use of power-of-two or non-power-of-two tables, i would be very interested in the result. joachim Am 24.07.2010 um 00:27 schrieb Victor Lazzarini: > I thought tablei only read pow-2 tables. > > Victor > On 23 Jul 2010, at 22:01, joachim heintz wrote: > >> hi - >> >> i see a littlebit strange behaviour of tablei. if it reads this >> function table ... >> giFt1 ftgen 1, 0, -10, -2, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.10 >> ... it says that index 9 is not a number. >> >> if i add an extra argument (which should actually be senseless), >> it's ok. >> >> is this a bug? or is it related to the size of the table (not a >> power of two - size=8 seems to be ok)? >> >> it works if i put the f-statement in the score, and tab_i instead >> of tablei works, too. >> >> joachim >> >> >> >> >> >> giFt1 ftgen 1, 0, -10, -2, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.10; "nan" >> giFt2 ftgen 2, 0, -10, -2, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.10, 0; ok >> instr 1 >> prints "%nFunction Table %d:%n", p4 >> indx init 0 >> loop: >> ival tablei indx, p4 >> prints "Index %d = %f%n", indx, ival >> loop_lt indx, 1, ftlen(p4), loop >> endin >> >> >> i 1 0 0 1 >> i 1 0 0 2 >> >> >> >> output: >> Function Table 1: >> Index 0 = 1.000000 >> Index 1 = 2.000000 >> Index 2 = 3.000000 >> Index 3 = 4.000000 >> Index 4 = 5.000000 >> Index 5 = 6.000000 >> Index 6 = 7.000000 >> Index 7 = 8.000000 >> Index 8 = 9.000000 >> Index 9 = nan >> Function Table 2: >> Index 0 = 1.000000 >> Index 1 = 2.000000 >> Index 2 = 3.000000 >> Index 3 = 4.000000 >> Index 4 = 5.000000 >> Index 5 = 6.000000 >> Index 6 = 7.000000 >> Index 7 = 8.000000 >> Index 8 = 9.000000 >> Index 9 = 10.100000 >> >> >> Send bugs reports to the Sourceforge bug tracker >> https://sourceforge.net/tracker/?group_id=81968&atid=564599 >> Discussions of bugs and features can be posted here >> To unsubscribe, send email sympa@lists.bath.ac.uk with body >> "unsubscribe csound" >> > > > > Send bugs reports to the Sourceforge bug tracker > https://sourceforge.net/tracker/?group_id=81968&atid=564599 > Discussions of bugs and features can be posted here > To unsubscribe, send email sympa@lists.bath.ac.uk with body > "unsubscribe csound" > > Send bugs reports to the Sourceforge bug tracker https://sourceforge.net/tracker/?group_id=81968&atid=564599 Discussions of bugs and features can be posted here To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound"

	this is my platform and csound version, too. it sounds ridiculous, but now i get the same output. i think my fault was actually that i meant "table" and not "tablei". i misinterpreted the "i" at the end as an initialization-i, not a interpolation-i. it makes sense that interpolation opcodes are looking for the next value, and it seems to be a bit ambivalent what they do if there is no next value like in my example. i just tried "table3", and it definitely does not work with the first table. thanks for the feedback - joachim Am 24.07.2010 um 00:43 schrieb Victor Lazzarini: > This is what I get here (OSX 10.5, 5.12.4 universal binary): > > Function Table 1: > Index 0 = 1.000000 > Index 1 = 2.000000 > Index 2 = 3.000000 > Index 3 = 4.000000 > Index 4 = 5.000000 > Index 5 = 6.000000 > Index 6 = 7.000000 > Index 7 = 8.000000 > Index 8 = 9.000000 > Index 9 = 10.100000 > Function Table 2: > Index 0 = 1.000000 > Index 1 = 2.000000 > Index 2 = 3.000000 > Index 3 = 4.000000 > Index 4 = 5.000000 > Index 5 = 6.000000 > Index 6 = 7.000000 > Index 7 = 8.000000 > Index 8 = 9.000000 > Index 9 = 10.100000 > > On 23 Jul 2010, at 22:01, joachim heintz wrote: > >> hi - >> >> i see a littlebit strange behaviour of tablei. if it reads this >> function table ... >> giFt1 ftgen 1, 0, -10, -2, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.10 >> ... it says that index 9 is not a number. >> >> if i add an extra argument (which should actually be senseless), >> it's ok. >> >> is this a bug? or is it related to the size of the table (not a >> power of two - size=8 seems to be ok)? >> >> it works if i put the f-statement in the score, and tab_i instead >> of tablei works, too. >> >> joachim >> >> >> >> >> >> giFt1 ftgen 1, 0, -10, -2, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.10; "nan" >> giFt2 ftgen 2, 0, -10, -2, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.10, 0; ok >> instr 1 >> prints "%nFunction Table %d:%n", p4 >> indx init 0 >> loop: >> ival tablei indx, p4 >> prints "Index %d = %f%n", indx, ival >> loop_lt indx, 1, ftlen(p4), loop >> endin >> >> >> i 1 0 0 1 >> i 1 0 0 2 >> >> >> >> output: >> Function Table 1: >> Index 0 = 1.000000 >> Index 1 = 2.000000 >> Index 2 = 3.000000 >> Index 3 = 4.000000 >> Index 4 = 5.000000 >> Index 5 = 6.000000 >> Index 6 = 7.000000 >> Index 7 = 8.000000 >> Index 8 = 9.000000 >> Index 9 = nan >> Function Table 2: >> Index 0 = 1.000000 >> Index 1 = 2.000000 >> Index 2 = 3.000000 >> Index 3 = 4.000000 >> Index 4 = 5.000000 >> Index 5 = 6.000000 >> Index 6 = 7.000000 >> Index 7 = 8.000000 >> Index 8 = 9.000000 >> Index 9 = 10.100000 >> >> >> Send bugs reports to the Sourceforge bug tracker >> https://sourceforge.net/tracker/?group_id=81968&atid=564599 >> Discussions of bugs and features can be posted here >> To unsubscribe, send email sympa@lists.bath.ac.uk with body >> "unsubscribe csound" >> > > > > Send bugs reports to the Sourceforge bug tracker > https://sourceforge.net/tracker/?group_id=81968&atid=564599 > Discussions of bugs and features can be posted here > To unsubscribe, send email sympa@lists.bath.ac.uk with body > "unsubscribe csound" > > Send bugs reports to the Sourceforge bug tracker https://sourceforge.net/tracker/?group_id=81968&atid=564599 Discussions of bugs and features can be posted here To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound"
