NumericUpDown SnapToMultipleOfInterval property does not work with decimal increments

[monoludic]

Using a NumericUpDown control with a decimal interval (eg 0.01) and SnapToMultipleOfInterval=True, incrementing using buttons produces values not rounded as expected.

IMHO, Value should be rounded to the nearest interval on each increment, otherwise errors are cumulated.
(0.01 + 0.01 + 0.01 + 0.01 + 0.01 + 0.01) == (0.01 * 6) is false on my computer.
