What is Math.BitDecrement() in C#?
C# has a built-in Math class which provides useful mathematical functions and operations. The class has the BitDecrement() function, which is used to compute the next smallest number less than a specified number.
Syntax
public static double BitDecrement (double value);
Parameters
- value: This is of the
Doubletype and represents the input value for which we have to findBitDecrement(). Its range is all double numbers.
Return value
- Double: This returns the next smallest number less than
value. - NaN: The function returns this for
NaNas an input ofvalue. - NegativeInfinity: The function returns this for
NegativeInfinityas an input ofvalue.
Example
using System;class Educative{static void Main(){Double result = Math.BitDecrement(10.1);System.Console.WriteLine("BitDecrement(10.1) = "+ result);Double result1 = Math.BitDecrement(Double.NaN);System.Console.WriteLine("BitDecrement(NaN) = "+ result1);Double result2 = Math.BitDecrement(Double.PositiveInfinity);System.Console.WriteLine("BitDecrement(∞) = "+ result2);}}
Output
- BitDecrement ( 10.1 ) = 10.099999999999998
- BitDecrement ( NaN ) = NaN
- BitDecrement ( -∞ ) = -∞
