then the one that is closest to positive infinity is returned. If the argument is NaN, then NaN is returned. If the argument
is positive infinity, then positive infinity is returned. If the argument is negative infinity, then negative infinity is
returned. If the argument is positive zero, then positive zero is returned. If the argument is negative zero, then negative
zero is returned. If the argument is less than zero, but greater than or equal to -0.5, then negative zero is returned.
