multipleOf throwing ValidationError for specific number

[vigneshkv23]

This is a strange issue. I have created a simple JSON schema to validate float which can be a maximum of two digits.

schema = {'type': 'number', 'multipleOf': 0.01}
jsonschema.validate(1.11, schema)

=>jsonschema.validate(1.11, schema)
Traceback (most recent call last):
File "", line 1, in
File "C:\Python38\lib\site-packages\jsonschema\validators.py", line 934, in validate
raise error
jsonschema.exceptions.ValidationError: 1.11 is not a multiple of 0.01

Observations-

1. From 1.11 till 1.19 throwing the validation error but from 1.21 No errors work as expected.
2. Again from 10.11 till 10.21 throwing the validation error but from 10.22 No errors work as expected.
3. 2.11 , 2.13 throwing the validation error
4. But the other number works fine.

Hi there -- this is expected behavior, see e.g. some of the previous issues linked here.

Essentially, if you don't want float division, use decimal.Decimal when you deserialize your JSON.
