* Fix for logb/logbf/logbl (bugs 13954/13955/13956)Adhemerval Zanella2012-05-101-14/+21
| | | | | | | | POSIX 2008 states that if the input for 'logb[f|l]' is a subnormal number it should be treated as if it were normalized. This means the implementation should calculate the log2 of the mantissa and add it to the subnormal exponent (-126 for float and -1022 for double and IBM long double). This patch takes care of that.
