| 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.)
