Elemental Intrinsic Function (Generic): Converts a value to integer type.
Syntax
result = INT (a [, kind])
a
(Input) Must be of type integer, real, or complex.
kind
(Input; optional) Must be a scalar integer initialization expression.
Results
The result type is 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:
If a is of type real and | a | 1, INT(a) is the integer whose magnitude is the largest integer that does not exceed the magnitude of a and whose sign is the same as the sign of a.

| 1 These specific functions cannot be passed as actual arguments. 2 This function can also be specified as HFIX. 3 The setting of compiler options specifying integer size or real size can affect IFIX. 4 For compatibility with older versions of Fortran, IFIX can also be specified as a generic function. 5 Or JINT. 6 The setting of compiler options specifying integer size can affect INT, IDINT, and IQINT. 7 Or JIFIX. 8 Or JIDINT. For compatibility with older versions of Fortran, IDINT can also be specified as a generic function. 9 Or JIQINT. For compatibility with older versions of Fortran, IQINT can also be specified as a generic function. 10 For compatibility, these functions can also be specified as generic functions. |
