Hi, SUSv2 specifies that MAXFLOAT be part of math.h. See here: http://www.opengroup.org/onlinepubs/007908799/xsh/math.h.html Could that be added, please? Like this, for example: #define MAXFLOAT ((float)3.40282346638528860e+38) (Which should match Intel architecture if my sources are right) Cheers Shawn
