In my Csound files (.csd) I set the tempo in the header like:

-t 90

It seems to work fine. One thing it won't do (Csound 6.04) is let me
use fractional tempi like 90.3 or whatever. I know the difference is
very subtle but Csound otherwise allows for tons of very subtle
differences so I was kind of surprised by this. I was wondering if
there was a reason for this or if maybe something was wrong on my end?
When I try to use a fractional tempo it comes back as an error.

I know I can change the durations if I want these fractional BPMs but
it's just nicer to have it in the tempo indicator.

Thanks for any information,
David Bellows

Hi David,

I think you may have the syntax incorrect for t-statements:

1. The statement should begin with "t" and not "-t".
2. The values that follow should be in pairs. For example, "t 0 60 4
90" would read as "at beat 0, tempo is 60, and at beat 4, tempo is
90".

This should be documented in the manual:

Hi Steven,

I am using the -t option in my  section as mentioned here:
http://csound.github.io/docs/manual/CommandFlags.html#FlagsMinusLowerT
and as I mentioned above it seems to work like I expect it to except
with fractional tempi. It's entirely possible I've completely
misunderstood the point of that command.

That said, moving it down to the score section like in your link the
fractional values now work. I now have code to rewrite!

So I guess the problem is solved.

Thank you very much!
Dave

It is entirely possible that the argument decode does not accept floats. Will look

Hi Dave,

Glad that worked out for you!  I see now what you mean about -t and
CsOptions and I had not realized you were talking about that.  As John
points out, there seems to be an issue with accepting floats.  I saw
in argdecode that there is:

              sscanf(s, "%d%n", &val, &n); /* use this tempo .. */

John: Perhaps we need to use %g ? I have perhaps a related issue
popping up now with Blue changes that I'll post to the developer's
list in a moment.

Yes will change as soon as I get the computer on

I have made the change including fix to OPARMS.  Also changed settempo to 
reflect  this
