INT — Convert to integer type

Description

Convert to integer type

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) 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.
(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
