Re: [Flashforth-devel] Floating point math for FF 5.x - special values

[om1zz <om...@vo...>]

We have problems with large numbers and alike results, it seems.

This test which worked with amforth crashes fs. :

\ large positive and negative
$ffff $ff7f fs. ." shall be -3.402823466e+38 " cr
$ffff $7f7f fs. ." shall be 3.402823466e+38 " cr

Moreover all tests where the result is undefined, and usualy returned above numbers (with my amforth asm float lib), returns now 0xffff 0x7fff from xc16 float, for example:

f-1.0 flog  ok<#,ram> 65535 32767
fpi/2 fasin  ok<#,ram> 65535 32767
fpi/2 facos  ok<#,ram> 65535 32767

what crashes fs. as well. So we must rethink how to print these states.
