toPaddedString(length[, radix]) -> String

Converts the number into a string padded with 0s so that the string’s length is at least equal to length. Takes an optional radix argument which specifies the base to use for conversion.

Examples

(13).toPaddedString(4);
// -> '0013'

(13).toPaddedString(2);
// -> '13'

(13).toPaddedString(1);
// -> '13'

(13).toPaddedString(4, 16)
// -> '000d'

(13).toPaddedString(4, 2);
// -> '1101'
