JavaScript 是否具有双浮点数精度? [英] Does JavaScript have double floating point number precision?

问题描述

我知道这是一个奇怪的问题，但是 JavaScript 是否有能力使用双精度而不是单浮点?(64 位浮点数与 32 位.)

I know it's an odd question, but does JavaScript have the capacity to work with double's as opposed to single floats? (64 bit floats vs. 32 bits.)

推荐答案

JavaScript 中的所有数字都是 64 位浮点数.

All numbers in JavaScript are 64-bit floating point numbers.
