| Description: | Returns the nearest integer to the argument. | ||
| Class: | Elemental function; Generic | ||
| Arguments: | A | Must be of type real. | |
| KIND (opt) | Must be a scalar integer initialization expression. | ||
| Results: | The result
is of type integer. If KIND is present, the
kind parameter of the result is that specified by KIND; otherwise, the kind
parameter of the result is shown in the following table. If the processor
cannot represent the result value in the kind of the result, the result
is undefined.
If A is greater than zero, NINT (A) has the value INT (A + 0.5); if A is less than or equal to zero, NINT (A) has the value INT (A - 0.5). | ||
| Specific Name | Argument Type | Result Type |
|---|---|---|
| ININT | REAL(4) | INTEGER(2) |
| NINT 1,2 | REAL(4) | INTEGER(4) |
| KNINT | REAL(4) | INTEGER(8) |
| IIDNNT | REAL(8) | INTEGER(2) |
| IDNINT 2,3 | REAL(8) | INTEGER(4) |
| KIDNNT | REAL(8) | INTEGER(8) |
| IIQNNT | REAL(16) | INTEGER(2) |
| IQNINT 2,4 | REAL(16) | INTEGER(4) |
| KIQNNT 5 | REAL(16) | INTEGER(8) |

1 Or JNINT.
2 The setting of compiler options specifying real size can affect NINT, IDNINT, and IQNINT. 3 Or JIDNNT. For compatibility with older versions of Fortran, IDNINT can also be specified as a generic function. 4 Or JIQNNT. For compatibility with older versions of Fortran, IQNINT can also be specified as a generic function. 5 This specific function cannot be passed as an actual argument. | ||
Examples
NINT (3.879) has the value 4.
NINT (-2.789) has the value -3.
