float 32 range

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

double and float are floating point types. Doubles (double type) are more accurate than float (single-precision) data and occupy more space. Double precision is twice times that of float, so a double is often used for more precise calculations.

Single-precision floating-point numbers are 4 bytes (32bit) representing floating point numbersUses the IEEE754 standard computer floating-point number, in the interior is uses the binary system to representFor example: 7.22 with a 32-bit binary is

IEEE754 the representation of floating-point numbers. The expression range of float type data in C language is -3.4*10^38~+3.4*10^38. Double is -1.7*10^-308~1.7*10^308,long double for -1.2*10^-4932~1.2*10^4932. Type Number of bits

A problem occurs when a program running properly on a 32-bit machine fails on a 64-bit machine. So I found this article about transplantation and took a good look. Original post address: http://queniao.blog.51cto.com/10636/126564 In fact, there is
