AINT(3f)

DESCRIPTION
AINT(A [, KIND]) truncates its argument to a whole number.

STANDARD
Fortran 77 and later

CLASS
Elemental function

SYNTAX
RESULT = AINT(A [, KIND])

ARGUMENTS

A The type of the argument shall be REAL. KIND (Optional) An INTEGER initialization expression indicating the kind parameter of the result.

RETURN VALUE
The return value is of type REAL with the kind type parameter of the argument if the optional KIND is absent; otherwise, the kind type parameter will be given by KIND. If the magnitude of X is less than one, AINT(X) returns zero. If the magnitude is equal to or greater than one then it returns the largest whole number that does not exceed its magnitude. The sign is the same as the sign of X.

EXAMPLE
          program test_aint
            real(4) x4
            real(8) x8
            x4 = 1.234E0_4
            x8 = 4.321_8
            print *, aint(x4), dint(x8)
            x8 = aint(x4,8)
          end program test_aint
