nextDown
Returns the floating-point value adjacent to f in the direction of negative infinity. This method is semantically equivalent to nextAfter(f, Float.NEGATIVE_INFINITY); however, a nextDown implementation may run faster than its equivalent nextAfter call.
Special Cases:
If the argument is NaN, the result is NaN.
If the argument is negative infinity, the result is negative infinity.
If the argument is zero, the result is
-Float.MIN_VALUE
Return
The adjacent floating-point value closer to negative infinity.
