Javascript中的单精度浮点仿真（float32） [英] Single precision float emulation in Javascript (float32)

问题描述

是否有可能以某种方式模拟Javascript中的单精度浮点数？根据Doug Crockford的博客Number is 64-bit floating point，但是我必须使用单一来移植C ++算法来计算单精度浮点数的误差。

Is it possible to somehow emulate single precision float in Javascript? According to Doug Crockford's blog "Number is 64-bit floating point", but I have to use single one for porting C++ algorithm which calculates single precision float's error.

推荐答案

ES6标准有Math.fround（），它将float64转换为float32然后再返回，有效地将float舍入为float32精度。有关详细信息，请参见本文。

The ES6 standard has Math.fround() which converts a float64 to float32 and then back again, effectively rounding the float to float32 precision. See this article for details.
