Module Quickjs.Number

JavaScript Number built-in object

This module mirrors the JavaScript Number API with prototype methods for number-to-string conversion.

type format =
  1. | Free
    (*

    Use minimum digits needed for exact round-trip

    *)
  2. | Fixed of int
    (*

    Use n significant digits (1-101)

    *)
  3. | Fractional of int
    (*

    Use n fractional digits (0-101)

    *)

Number of digits to use

type exponent =
  1. | Auto
    (*

    Use exponential when appropriate

    *)
  2. | Always
    (*

    Always use exponential notation

    *)
  3. | Never
    (*

    Never use exponential notation

    *)

Exponential notation control

type options = {
  1. format : format;
  2. exponent : exponent;
  3. radix : int;
  4. show_minus_zero : bool;
}

Full options for formatting

val default_options : options

Default options: Free format, Auto exponent, radix 10, no minus zero
