Function Summary

DESCRIPTION

These functions constitute the C math library, libm. The link editor searches this library under the -lm option. Declarations for these functions may be obtained from the include file <math.h>.

NOTES

The math library can handle floating point exceptions in different ways depending upon the level of standards conformance that the user desires. The math library currently supports the following personality modes: 

XOPEN
POSIX
SVID
IEEE

For details on these personality modes, see the _NutLibMSetLibraryType() reference page.
