How Small Can A Javascript Number Be Without Displaying In Scientific Notation?

Post a Comment
I've made some code that rounds off a number to a given number of decimal places but will use more places when there is underflow to avoid rounding just to zero, which wouldn't be

Solution 1:

There are a few reasons the number is displayed in scientific notation:

  • If the length of significant digits in the number is greater than 21.
  • If the number of zeros before a nonzero number is greater than 6. (e.g. 0.00000001)

The conversion to scientific notation in numbers is specified in Section 9.8.1 of ECMA-262.

An implementation of this specification can be found in the V8 engine here.
