A 32-bit integer can store values from −2^31 (MIN_VALUE) to 2^31 − 1
(MAX_VALUE). JavaScript converts a Number (a 64-bit floating point number)
to a 32-bit integer (int32) when bitwise operators (such as |) are
applied. Use is to check is a number can be represented as a 32-bit integer.
Sign-based operations include signEqual and abs. Power/logarithm
related operations include isPow2, prevPow2, nextPow2, pow2, pow10,
log2, and log10.
This package is available in Node.js and Web formats. The web format
is exposed as extra_integer standalone variable and can be loaded from
jsDelivr CDN.
Stability: Experimental.
const integer = require('extra-integer');
// import * as integer from "extra-integer";
// import * as integer from "https://unpkg.com/extra-integer/index.mjs"; (deno)
integer.is(9.11e-31);
// → false
integer.log10(10000);
// → 4
integer.nextPow2(63);
// → 64Index
