Context

• node version: v12.18.1

What are you trying to achieve or the steps to reproduce?

const schema = Joi.number()
const result = schema.validate('00000')

This affects a system that exchange messages that may contain padded numbers with a fixed length. even though there is a regex to remove leading zeros in the normalizeDecimal function, it only accounts for non zero integers.

What was the result you got?

error type 'number.unsafe'

What result did you expect?

{ error: null, value: 0 }
