Incorrect implementation on 'Multiple of'

[zenkio]

I have this in my schema:

"amount": {
                "type": "number",
                "multipleOf": 0.01
              },

The generated Validate function is

if math.Mod(*m.Amount, 0.01) != 0 {
		return &validationError{
			errType:  "multipleOf",
			path:     []interface{}{"Amount"},
			jsonPath: []interface{}{"amount"},
			message:  fmt.Sprintf("must be a multiple of 0.01 but was %v", *m.Amount),
		}
	}

So for the amount 2000, it reported the error as must be a multiple of 0.01 but was 2000

I understand the floating point characteristic makes an integer won't always return 0 when calculating math.Mod(integer, 0.01)

I have to modify it manually to correct the validation.

if math.Mod(*m.Amount*100, 1) != 0 {
		return &validationError{
			errType:  "multipleOf",
			path:     []interface{}{"Amount"},
			jsonPath: []interface{}{"amount"},
			message:  fmt.Sprintf("must be a multiple of 0.01 but was %v", *m.Amount),
		}
	}
