Unique situations: If possibly argument is often a NaN, then NaN is returned. If equally arguments are signed zeros, a value equivalent to route is returned. If start out is ±Float.MIN_VALUE and way has a worth this kind of that The end result ought to have a smaller magnitude, then a zero Using the very same indicator as start out is returned.
Returns the better of two float values. That's, The end result may be the argument closer to beneficial infinity. If the arguments possess the identical worth, the result is that same value.
