IEEE_SIGNALING_GE

Elemental Module Intrinsic Function (Generic): Performs a signaling comparison for greater than or equal. This is equivalent to the IEEE compareSignalingGreaterEqual operation.

Module

USE, INTRINSIC :: IEEE_ARITHMETIC

result = IEEE_SIGNALING_GE (a,b)

a

(Input) Must be of type REAL.

b

(Input) Must be of type REAL with the same kind type parameter as a.

Results

The result type is default LOGICAL. It has the value true if a compares greater than or equal to b. If a or b is a NaN, the result is false and IEEE_INVALID signals, otherwise no exception is signaled.

This is the compareSignalingGreaterEqual operation as specified in the ISO/IEC/IEEE 60559:2011 standard.

Example

The result value of IEEE_SIGNALING_GE (3.7, IEEE_VALUE (0.0, IEEE_QUIET_NAN)) is false and IEEE_INVALID is signaled.
