Hello floating point lib users:
there is a BUG in file cmpsf.c:
The return code 0 for equal floats is returned only if these two floats
a1, and a2 are 0. In this case, both float zeros, i.e. +0 and -0 are be
equal to each other.
If two equal floats are not 0, then either code 1 or code -1 is
returned, depending on the sign of these (equal) floats. This is
obviously wrong, since return code 0 has to used in this case.
The BUG can be resolved by adding this code at line 40 to cmpsf.c:
if (a1==a2) return 0;
Add this code to cmpsf.c e.g. at line 40, which is empty now.
Must be added before line 41 that checks for both arguments less than
0: if(a1<0 && a2<0) ....
File with BUG resolved was tested in application and works proper now.
Best regards, Volker Schindler.
