`E` and `e` can be used interchangeably for exponents of floating-point literals in Java . A suffix of `F` or `f` indicates a single-precision (32-bit) literal. A suffix of `D` or `d` (or no suffix) indicates a double-precision (64-bit) literal.

This is also the case in C (and C++, and Objective-C) — `E` and `e` can be used interchangeably — but there isn’t a special suffix for double-precision numbers (floating-point literals with no suffix are double-precision). JavaScript , PHP , and Python 

Thanks John and Nate for that.  I'll probably audit Blue to ensure
printing of doubles doesn't use exponential notation, but I think it
would be good to have support for 'E' as I can imagine this popping up
for other users.

Thanks John too for looking into this!
