representation

How does a .NET decimal type get represented in binary in memory? We all know how floating-point numbers are stored and the thusly the reasons for the inaccuracy thereof, but I can't find any information about decimal except the following: Apparently more accurate than floating-point numbers Takes 128 bits of memory 2^96 + sign range 28 (sometimes 29?) total significant digits in the number Is there any way I can figure this out? The computer scientist in me demands the answer and after an hour of attempted research, I cannot find it. It seems like there's either a lot of wasted bits or I'm

I want to represent a floating-point number as a string rounded to some number of significant digits, and never using the exponential format. Essentially, I want to display any floating-point number and make sure it “looks nice”. There are several parts to this problem: I need to be able to specify the number of significant digits. The number of significant digits needs to be variable, which can't be done with with the string formatting operator . [edit] I've been corrected; the string formatting operator can do this. I need it to be rounded the way a person would expect, not something like 1

Still learning C and I was wondering: Given a number, is it possible to do something like the following? char a = 5; printf("binary representation of a = %b",a); > 101 Or would i have to write my own method to do the transformation to binary? Yes (write your own), something like the following complete function. #include <stdio.h> /* only needed for the printf() in main(). */ #include <string.h> /* Create a string of binary digits based on the input value. Input: val: value to convert. buff: buffer to write to must be >=

I know that a boolean value is 1 byte (8 bits long) But I would like to know is what is its binary representation. e.g. decimal => binary 4 => 100 (0000 0100) 8 => 1000 (0000 1000) bool value => ??? bool is a built-in basic type in C#. Any underlying representation would be an implementation detail. The C# 4.0 Language Specification states in section 4.1.8: The bool type represents boolean logical quantities. The possible values of type bool are true and false . No standard conversions exist between bool and other types. In particular, the bool type is distinct and separate from the integral
