# IEEE_IS_NORMAL

Elemental Module Intrinsic Function (Generic): Returns whether an IEEE value is normal.

## Module

USE, INTRINSIC :: IEEE_ARITHMETIC

result = IEEE_IS_NORMAL (x)

x | (Input) Must be of type REAL.

## Results

The result type is default logical. The result has the value true if the value of x is normal; otherwise, false.

An IEEE value is normal if IEEE_CLASS(x) has one of the following values:

IEEE_POSITIVE_NORMAL | IEEE_POSITIVE_ZERO
IEEE_NEGATIVE_NORMAL | IEEE_NEGATIVE_ZERO

## Example

IEEE_IS_NORMAL (SQRT(-2.0)) has the value false if IEEE_SUPPORT_SQRT (-2.0) has the value true.
