Module number 

JavaScript-compatible number parsers and formatters.

Functions

format_number_js

ECMAScript ToString for f64 — spells NaN/Infinity/-Infinity and normalizes -0 to “0” (Rust’s default prints “inf” and keeps the sign).

parse_float_js

parse_int_js

JS-spec parseInt(s, radix) for an already-converted radix.

parse_int_with_radix

parseInt(s, radix) with the radix argument as JavaScript reads it: ToInt32, where 0 (including NaN and an omitted radix) means “detect a 0x prefix, else base 10”. Any other value outside 2–36 makes the result NaN.

string_to_number_js

JS-spec Number(s) / ToNumber on a string.

to_exponential_js

JS-spec Number#toExponential(fractionDigits). A NaN fractionDigits is the omitted-argument sentinel: use however many digits uniquely identify the value.

to_fixed_js

JS-spec Number#toFixed(digits).

to_precision_js

JS-spec Number#toPrecision(precision). A NaN precision is the omitted-argument sentinel: behave like plain toString.

to_string_radix_js

JS-spec Number#toString(radix) for radix 2–36.
