# Use Exponents

If your language has an exponent operator you might be able to use it to generate, if not the number you want, at least a number you can perform a simple calculation or 2 on to arrive at your number. Even without an operator, you may still be able to save bytes with a built-in function or method.

## Example
The [maximum safe integer in JavaScript](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Number/MAX_SAFE_INTEGER) is `9007199254740991`, which is 16 digits long. In ES7, this can be calculated with the following 7 bytes:

    2**53-1

The equivalent in ES6 and earlier, while the same length as the integer itself in this instance, demonstrates that using a more verbose method might not necessarily cost you any bytes.

    Math.pow(2,53)-1

The above, though, may work out *shorter* if, for example, you already have `Math` aliased to a single character elsewhere in your code.
