REAL function, the
KIND= value of the type being that of argument A.
REAL; scalar; INTENT(IN).
Intrinsic groups: (standard FORTRAN 77).
Returns A with the fractional portion of its magnitude eliminated by rounding to the nearest whole number and with its sign preserved.
A fractional portion exactly equal to
.5 is rounded to the whole number that
is larger in magnitude.
(Also called "Fortran round".)
See AInt Intrinsic, for how to truncate to whole number.
See NInt Intrinsic, for how to round and then convert
