# IEEE_SUPPORT_STANDARD

Inquiry Module Intrinsic Function (Generic): Returns whether the processor supports IEEE features defined in the standard.

## Module

USE, INTRINSIC :: IEEE_ARITHMETIC

result = IEEE_SUPPORT_STANDARD ([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. The result has the value true if the results of all the following functions are true (x can be omitted):

IEEE_SUPPORT_DATATYPE([x])
IEEE_SUPPORT_DENORMAL([x])
IEEE_SUPPORT_DIVIDE([x])
IEEE_SUPPORT_FLAG(flag [, x])1
IEEE_SUPPORT_HALTING(flag)1
IEEE_SUPPORT_INF([x])
IEEE_SUPPORT_NAN([x])
IEEE_SUPPORT_ROUNDING(round_value [, x])2
IEEE_SUPPORT_SQRT([x])
1 "flag" must be a valid value 2 "round_value" must be a valid value

Otherwise, the result has the value, false.

## Example

IEEE_SUPPORT_STANDARD () has the value false if both IEEE and non-IEEE real kinds are supported.
