Single precision float emulation in Javascript (float32)

Question

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.

Answer 1

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.
