IEEE_SUPPORT_UNDERFLOW_CONTROL

Inquiry Module Intrinsic Function (Generic): Returns whether the processor supports the ability to control the underflow mode.

Module

USE, INTRINSIC :: IEEE_ARITHMETIC

result = IEEE_SUPPORT_UNDERFLOW_CONTROL ([x])

x

(Input; optional) Must be of type REAL; it can be scalar or array valued.

Results

The result is a scalar of type default logical. If x is omitted, the result has the value true if the processor supports controlling the underflow mode for all real values; otherwise, false.

If x is specified, the result has the value true if the processor supports controlling the underflow mode for real variables of the same kind type parameter as x; otherwise, false.

Example

IEEE_SUPPORT_UNDERFLOW _CONTROL () has the value true if controlling the underflow mode is supported for all real types.
