! 13.7.53    INT(A [, KIND])
4 
!
5 
! Description.  Convert to integer type.
6 
! Class.       Elemental function.
7 
! Arguments.
8 
!    A               shall be of type integer, real, or complex,
9 
!                    or a boz-literal-constant .
10 
!    KIND (optional) shall be a scalar integer initialization expression.
11 
!
12 
! Result Characteristics. Integer. If KIND is present, the kind type
13 
!    parameter is that specified by the value of KIND; otherwise, the
14 
!    kind type parameter is that of default integer type.
15 
!
16 
! Result Value.
17 
!
18 
!    Case (1):  If A is of type integer, INT (A) = A.
19 
!
20 
!    Case (2):  If A is of type real, there are two cases:
21 
!      (a) if |A| < 1, INT (A) has the value 0
22 
!      (b) if |A| .ge. 1, INT (A) is the integer whose magnitude is the
23 
!          largest integer that does not exceed the magnitude of A and
24 
!          whose sign is the same as the sign of A.
25 
!
26 
!    Case (3):  If A is of type complex, INT(A) = INT(REAL(A, KIND(A))).
27 
!
28 
!    Case (4):  If A is a boz-literal-constant, it is treated as if it were
29 
!               an int-literal-constant with a kind-param that specifies the
30 
!               representation method with the largest decimal exponent range
31 
!               supported by the processor.
32 
!
33 
!    Example. INT (­3.7) has the value ­3.
