Safe Integer Number

Safe integer number primitive

<tt>safe-integer/coerce</tt>

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 

<tt>safe-integer/ensure</tt>

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
