2012-05-05fix definitions of FP_ILOGB constantsRich Felker1-2/+2
two issues: (1) the type was wrong (unsigned instead of signed int), and (2) the value of FP_ILOGBNAN should be INT_MIN rather than INT_MAX to match the ABI. this is also much more useful since INT_MAX corresponds to a valid input (infinity). the standard would allow us to set FP_ILOGB0 to -INT_MAX instead of INT_MIN, which would give us distinct values for ilogb(0) and ilogb(NAN), but the benefit seems way too small to justify ignoring the ABI. note that the macro is just a "portable" (to any twos complement system where signed and unsigned int have the same width) way to write INT_MIN without needing limits.h. it's valid to use this method since these macros are not required to work in #if directives.
