multipleOf doesn't work for smaller multiples due to precision

[deep-creek]

When defining a schema like this:
{ "$schema": "http://json-schema.org/draft-04/schema#", "id": "https://example.com/multipleOf", "type": "object", "properties": { "myNumber": { "type": "number", "multipleOf": 0.1 } }, "required": [ "myNumber" ] }

And a test like this:
func TestExampleJson_UnmarshalJSON(t *testing.T) { json :={"myNumber": 148.1}`

a := ExampleJson{}
err := a.UnmarshalJSON([]byte(json))

assert.NoError(t, err)

}
`

The decoding fails with an error. That is due to math.Abs(math.Mod(plain.MyNumber, 0.1)) returning 0.0999999999999861 instead of something lower than 1e-10.

The decoding code should not be:
if math.Abs(math.Mod(plain.MyNumber, 0.1)) > 1e-10 { return fmt.Errorf("field %s: must be a multiple of %v", "myNumber", 0.100000) }
but instead be:
{ remainder := math.Mod(plain.MyNumber, 0.1) if !(math.Abs(remainder) < 1e-10 || math.Abs(remainder-0.1) < 1e-10) { return fmt.Errorf("field %s: must be a multiple of %v", "myNumber", 0.100000) } }
