# IEEE_IS_NEGATIVE

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

## Module

USE, INTRINSIC :: IEEE_ARITHMETIC

result = IEEE_IS_NEGATIVE (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 negative; otherwise, false.

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

IEEE_NEGATIVE_NORMAL | IEEE_NEGATIVE_ZERO
IEEE_NEGATIVE_DENORMAL | IEEE_NEGATIVE_INF

## Example

IEEE_IS_NEGATIVE (2.0) has the value false.
