8.125 INT — Convert to integer type

Description:
Convert to integer type
Standard:
Fortran 77 and later
Class:
Elemental function
Syntax:
RESULT = INT(A [, KIND))
Arguments:

A Shall be of type INTEGER, REAL, or COMPLEX.
KIND (Optional) An INTEGER initialization expression indicating the kind parameter of the result.

Return value:
These functions return a INTEGER variable or array under the following rules:
(A)
If A is of type INTEGER, INT(A) = A
(B)
If A is of type REAL and |A| < 1, INT(A) equals 0. If |A| \geq 1, then INT(A) equals the largest integer that does not exceed the range of A and whose sign is the same as the sign of A.
(C)
If A is of type COMPLEX, rule B is applied to the real part of A.

Example:
          program test_int
            integer :: i = 42
            complex :: z = (-3.7, 1.0)
            print *, int(i)
            print *, int(z), int(z,8)
          end program
