/**
 * Limit decimals of a floating number to specified length. The length depends on
 * `decimals` which can have the following settings (n = integer):
 *
 * Char | Description
 * ----- | -------------
 * **>n** | Minimum number of decimals, if the current number of decimals are shorter than the defined length, extra 0 (zeros) will be added.
 * **<n** | Maximum number of decimals, longer decimals will be rounded and shortened down to this number.
 * **n** | Match this exact number of decimals, rounding longer decimals and adding extra 0 (zeroes) to shorter ones.
 *
 * @example
 * ```ts
 * // Exact number of decimals
 * limitDecimals(123.4567) // -> 123.46
 * limitDecimals(123, 5) // -> 123.00000
 *
 * // Max number of decimals
 * limitDecimals(123.4567, '<3') // -> 123.457
 * limitDecimals(123, '<3') // -> 123
 *
 * // Min number decimals
 * limitDecimals(123.4, '>4') // -> 123.4000
 * limitDecimals(123.456789, '>4') // -> 123.456789
 * ```
 *
 * @param num - Number to limit the decimals on
 * @param decimals - Setting for how to handle the decimals
 * @return - String representation of the number with the decimals adjusted according to the decimal setting
