General description

The isgreaterequal() macro or function template determines whether the argument x is greater than or equal to y. It is equivalent to (x) >= (y), but no exception is raised if x or y are NaN.

Function Hex IEEE
isgreaterequal X X
Notes:
  1. To use IEEE decimal floating-point, the hardware must have the Decimal Floating-Point Facility installed.
  2. This function works in IEEE decimal floating-point format. See "IEEE Decimal Floating-Point" for more information.

Returned value

The isgreaterequal() macro returns 1 if the value of x is greater than or equal to y, else returns 0. The C++ function template returns true if the value of x is greater than or equal to y, else returns false.
