isgreaterequal()

Arguments:

x, y

The floating-point numbers that you want to compare.

Library:

libm

The general-purpose math library.

libm-sve

A library that optimizes the code for ARMv8.2 chips that have Scalable Vector Extension hardware.

Your system requirements will determine how you should work with these libraries:

• If you want only selected processes to run with the SVE version, you can include both libraries in your OS image and use the -l m or -l m-sve option to qcc to link explicitly against the appropriate one.
• If you want all processes to use the SVE version, include libm-sve.so in your OS image and set up a symbolic link from libm.so to libm-sve.so. Use the -l m option to qcc to link against the library.

Description:

The isgreaterequal() macro determines whether x is greater than or equal to y. It's the same as (x) >= (y) but doesn't raise the invalid floating-point exception if x and y are unordered.

Returns:

The value of (x) >= (y). If x or y is NaN, this function returns 0.

Classification:

C11, POSIX 1003.1
