Description

       These functions return the larger value of x and y.

Errors

       No errors occur.

History

       glibc 2.1.  C99, POSIX.1-2001.

Library

       Math library (libm, -lm)

Name

       fmax, fmaxf, fmaxl - determine maximum of two floating-point numbers

Return Value

       These functions return the maximum of x and y.

       If one argument is a NaN, the other argument is returned.

       If both arguments are NaN, a NaN is returned.

Standards

       C11, POSIX.1-2008.
