how to convert float to binary

Both int and float are 4-byte, 32-bit representations. Why is the range of float greater than int?Float precision is 6~7 bit. 1.66*10^10 's numerical results are not 166 0000 0000, the larger the error.These problems are caused by the way

First, only string is associated with the encoding; When converting between byte and other types, be aware of big or small endpoints. Encoding: Ascii Unicode gbk utf-8 et cetera A byte of 8 digits can be composed of two 16-digit (0XFF), a 16-bit

Sorry, I used such a "two" question, but I hope the content is not too much.Actually, those who have learned programming are not familiar with these three things. Int is also called an integer. In. net, it refers to int32, which is a 32-bit signed

Reference: http://blog.csdn.net/candadition/article/details/7342380Converting a string type to an int, float, double type is primarily done in the following ways:# method One: Use StringStreamStringStream has been introduced in methods that convert

Package test1;public class Test2 {/*** @param args*/public static void Main (string[] args) {Float xx = 2.0f;Float yy = 1.8f;Float tt = XX-YY;System.out.println ("tttttt-----" + TT);}}Sure enough, the result is: TTTTTT-----0.20000005Again testing

Let's talk about the binary algorithm in the computer: IntegerWe should be familiar with the binary algorithm of integers, that is, dividing them by two to get the remainder, and then sorting the remainder in reverse order. For example, calculate

1. ScopeThe float and double ranges are determined by the number of digits of the index.The float index has eight digits, while the double index has 11 digits. The distribution is as follows:Float:1bit (symbol bit) 8 bits (index bit) 23 bits (tail

In the project, the float type is used to define some columns, such as price, but many problems are found.1. When the number of bits on the value is greater than 6, the float type is converted to the varchar type, which is displayed in the
