padZero(str, len [, isRight]) pads a string with zeros up to a specified length will not pad a string if its length is aready greater than or equal to the specified length default output pads with zeros on the left set isRight to `true` to pad with zeros on the right
padZero ( str len [ isRight ] ) pads a string with zeros up to a specified length will not pad a string if its length is aready greater than or equal to the specified length default output pads with zeros on the left set isRight to true to pad with zeros on the right
