# IEEE_CLASS

Elemental Module Intrinsic Function (Generic): Returns the IEEE class.

## Module

USE, INTRINSIC :: IEEE_ARITHMETIC

result = IEEE_CLASS (x)

x | (Input) Must be of type REAL.

## Results

The result is of type TYPE(IEEE_CLASS_TYPE). The result value is one of the following:

IEEE_SIGNALING_NAN | IEEE_NEGATIVE_NORMAL
IEEE_QUIET_NAN | IEEE_POSITIVE_DENORMAL
IEEE_POSITIVE_INF | IEEE_NEGATIVE_DENORMAL
IEEE_NEGATIVE_INF | IEEE_POSITIVE_ZERO
IEEE_POSITIVE_NORMAL | IEEE_NEGATIVE_ZERO

IEEE_CLASS does not return IEEE_OTHER_VALUE in Intel® Fortran.

## Example

IEEE_CLASS(1.0) has the value IEEE_POSITIVE_NORMAL.
