# IEEE_SUPPORT_FLAG

Transformational Module Intrinsic Function (Generic): Returns whether the processor supports IEEE exceptions.

## Module

USE, INTRINSIC :: IEEE_EXCEPTIONS

result = IEEE_SUPPORT_FLAG (flag [, x])

flag | (Input) Must be a scalar of type TYPE (IEEE_FLAG_TYPE). Its value is one of the following IEEE flags: IEEE_DIVIDE_BY_ZERO, IEEE_INEXACT, IEEE_INVALID, IEEE_OVERFLOW, or IEEE_UNDERFLOW.
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 detection of the exception specified by flag for all real values; otherwise, false.

If x is specified, the result has the value true if the processor supports detection of the exception specified by flag for real variables of the same kind type parameter as x; otherwise, false.

## Example

IEEE_SUPPORT_FLAG (IEEE_UNDERFLOW) has the value true if the IEEE_UNDERFLOW exception is supported for all real types.
