任何一种双倍获得超过13个小数点的方法？ C＃还是JS？

Question

is there any way i can get a double to contain more than default 13 (17 in JS) decimal points in C# or JS? Like a double with first 25 PI digits?

Answer 1

Standard Data Types

Both the double in C# and he normal number data type in JavaScript is stored as 64 bit number, see https://www.w3schools.com/js/js_numbers.asp and https://www.tutorialspoint.com/csharp/csharp_data_types.htm

This limits the number of decimal points that can be represented. However, there are appropriate Libraries to handle this issue

Possible Solutions

There are numerous libraries that handle large numbers and high precision floating point numbers.

• JavaScript see the answer here: What is the standard solution in JavaScript for handling big numbers (BigNum)? .

• C# See the answers here: Is there a BigFloat class in C#?
