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.
