Safe Integer Number

Safe integer number primitive

safe-integer/coerce

Follows integer/coerce but returns null in place of values which are beyond Number.MIN_SAFE_INTEGER and Number.MAX_SAFE_INTEGER range.

const coerceToSafeInteger = require("type/safe-integer/coerce");

coerceToInteger("12.95"); // 12
coerceToInteger(9007199254740992); // null
coerceToInteger(null); // null

safe-integer/ensure

If given argument is a safe integer coercible value (via safe-integer/coerce) returns result number.
Otherwise TypeError is thrown.

const ensureSafeInteger = require("type/safe-integer/ensure");

ensureSafeInteger(12.93); // "12"
ensureSafeInteger(9007199254740992); // Thrown TypeError: null is not a safe integer
