Incorrectly formatted error message for multipleOf

Given the following schema:
`{
    "type": "object",
    "properties": {
        "value1": {
            "type": "number",
            "multipleOf": 0.00001
        }
    }
}`

and the following input:
`{"value1":123.000001}`

the library is returning the following error message:
must be multiple of 0

but it should be: "must be multiple of 0.00001"
