| Description: | Converts a value to integer type. | ||
| Class: | Elemental function; Generic | ||
| Arguments: | A | Must be of type integer, real, or complex. | |
| 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.
Functions that cause conversion of one data type to another type have the same affect as the implied conversion in assignment statements. The result value depends on the type and absolute value of A, as follows:

1 These specific functions cannot be passed as actual
arguments.
2 This function can also be specified as HFIX. 3 For compatibility with older versions of Fortran, IFIX can also be specified as a generic function. 4 The setting of compiler options specifying real size or integer size can affect IFIX. 5 Or JINT. 6 The setting of compiler options specifying real size can affect INT, IDINT, and IQINT. 7 Or JIDINT. For compatibility with older versions of Fortran, IDINT can also be specified as a generic function. 8 Or JIQINT. For compatibility with older versions of Fortran, IQINT can also be specified as a generic function. | ||
Examples
INT (-4.2) has the value -4.
INT (7.8) has the value 7.
