SYNTAX

result = int(a [, kind))

DESCRIPTION

Convert to integer type

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:

1. If A is of type INTEGER, int(a) = a
2. If A is of type REAL and |a| < 1, int(a) equals 0. If |a| >= 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.
3. If A is of type COMPLEX, rule 2 is applied to the real part of A.

EXAMPLE

Sample program: 

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