## 9.3.108 NEAREST (X, S)

Description: | Returns the nearest different number (representable on the processor) in a given direction.
Class: | Elemental function; Generic
Arguments: | X | Must be of type real.
| S | Must be of type real and nonzero.
Results: | The result type is the same as X. The result has a value equal to the machine representable number that is different from and nearest to X, in the direction of infinity, with the same sign as S.

Examples

If 3.0 and 2.0 are REAL(4) values, NEAREST (3.0, 2.0) has the value 3 + 2-22, which equals approximately 3.0000002. (For more information on the model for REAL(4), see Section D.2.)
