AINT — Truncate to a whole number#
-
AINT(A[
, KIND
])# AINT(A [, KIND])
truncates its argument to a whole number.- Parameters
A – The type of the argument shall be
REAL
.KIND – (Optional) An
INTEGER
initialization expression indicating the kind parameter of the result.
- Returns
The return value is of type
REAL
with the kind type parameter of the argument if the optionalKIND
is absent; otherwise, the kind type parameter will be given byKIND
. If the magnitude ofX
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 ofX
.
- Standard:
