To subscribe to this RSS feed, copy and paste this URL into your RSS reader. If the ToString(Int32, Int32) method is called to create a string that will later be converted back to a number, a corresponding method that assumes a similar numeric representation should be called to perform the conversion. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. In the loop, we calculate the remainders and quotients to convert the decimal number to its binary equivalent, as shown above. The atoi () function neglects all white spaces at the beginning of the string, converts the characters after the white spaces, and then stops when it reaches the first non-number character. First define some mnemonics for your bits: Then you have your number you want to convert to a bit string: You can check if a bit is set by using the logical & operator.

It returns Boolean.TrueString for true values and Boolean.FalseString for false values. New number is 10/2 = 5. Because the "G" specifier by default outputs only decimal digits in a byte value's string representation, the provider parameter does not affect the formatting of the returned string. I did retain filling the buffer from end to beginning because it seems like a logical flow to me and requires one less variable to deal with. Therefore the equivalent binary number is 1010. This implementation is identical to Double.ToString(). The following example converts a Decimal to a String.
