! 13.7.53 INT(A [, KIND])
!
! Description. Convert to integer type.
! Class. Elemental function.
! Arguments.
! A shall be of type integer, real, or complex,
! or a boz-literal-constant .
! KIND (optional) shall be a scalar integer initialization expression.
!
! Result Characteristics. Integer. If KIND is present, the kind type
! parameter is that specified by the value of KIND; otherwise, the
! kind type parameter is that of default integer type.
!
! Result Value.
!
! Case (1): If A is of type integer, INT (A) = A.
!
! Case (2): If A is of type real, there are two cases:
! (a) if |A| < 1, INT (A) has the value 0
! (b) if |A| .ge. 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.
!
! Case (3): If A is of type complex, INT(A) = INT(REAL(A, KIND(A))).
!
! Case (4): If A is a boz-literal-constant, it is treated as if it were
! an int-literal-constant with a kind-param that specifies the
! representation method with the largest decimal exponent range
! supported by the processor.
!
! Example. INT (3.7) has the value 3.
