Class:
Elemental function
Syntax:
RESULT = NINT(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:
Returns A with the fractional portion of its magnitude eliminated by rounding to the nearest whole number and with its sign preserved, converted to an INTEGER of the default kind.
Example:
          program test_nint
            real(4) x4
            real(8) x8
            x4 = 1.234E0_4
            x8 = 4.321_8
            print *, nint(x4), idnint(x8)
          end program test_nint
