 * Converts a `Number` into a `String` with a given number of digits.`nf()` converts numbers such as `123.45` into strings formatted with a set
 * number of digits, as in `'123.4500'`.The first parameter, `num`, is the number to convert to a string. For
 * example, calling `nf(123.45)` returns the string `'123.45'`. If an array of
 * numbers is passed, as in `nf([123.45, 67.89])`, an array of formatted
 * strings will be returned.The second parameter, `left`, is optional. If a number is passed, as in
 * `nf(123.45, 4)`, it sets the minimum number of digits to include to the
 * left of the decimal place. If `left` is larger than the number of digits in
 * `num`, then unused digits will be set to 0. For example, calling
 * `nf(123.45, 4)` returns the string `'0123.45'`.The third parameter, `right`, is also optional. If a number is passed, as
 * in `nf(123.45, 4, 1)`, it sets the minimum number of digits to include to
 * the right of the decimal place. If `right` is smaller than the number of
 * decimal places in `num`, then `num` will be rounded to the given number of
 * decimal places. For example, calling `nf(123.45, 4, 1)` returns the string
 * `'0123.5'`. If right is larger than the number of decimal places in `num`,
 * then unused decimal places will be set to 0. For example, calling
 * `nf(123.45, 4, 3)` returns the string `'0123.450'`.When the number is negative, for example, calling `nf(-123.45, 5, 2)`
 * returns the string `'-00123.45'`.
