Module Quickjs.GlobalSource

JavaScript Global object functions

This module contains global functions from the JavaScript specification like parseFloat and parseInt.

Sourcetype parse_options = {
  1. radix : int;
    (*

    0 = auto-detect, 2-36 = fixed radix

    *)
  2. int_only : bool;
    (*

    Only accept integers (no dot, no exponent)

    *)
  3. accept_bin_oct : bool;
    (*

    Accept 0b and 0o prefixes when radix=0

    *)
  4. accept_legacy_octal : bool;
    (*

    Accept 0777 style (Annex B) when radix=0

    *)
  5. accept_underscores : bool;
    (*

    Accept 1_000_000 as digit separator

    *)
}

Parsing options for string-to-number conversion

Sourceval default_parse_options : parse_options

Default options: radix 10, no special parsing

Sourceval js_parse_options : parse_options

JavaScript-compatible options: auto-detect radix, accept 0b/0o prefixes

Sourceval parse_float : ?options:parse_options -> string -> float option

parse_float ?options str parses string str as a floating-point number. Returns None if parsing fails. Equivalent to JavaScript's parseFloat().

Sourceval parse_float_partial : ?options:parse_options -> string -> (float * string) option

parse_float_partial ?options str parses the beginning of string str as a floating-point number, returning the parsed value and remaining string. Returns None if no valid number is found at the start.

Sourceval parse_int : ?radix:int -> string -> int option

parse_int ?radix str parses string str as an integer. radix specifies the base (2-36), or 0 for auto-detect. Default is 10. Returns None if parsing fails or radix is invalid. Equivalent to JavaScript's parseInt().
