Is there a way to give partial credit for a Numeric question in New Quizzes?

Here's my specific example:

(Prior problem context elided)
Defining dynamic range as \(\lceil\log_2\frac{N_{\max}}{N_{\min}}\rceil\), what is the dynamic range of fp16?

The correct answer was 30. The question was worth 4 points.

A lot of students didn't do the ceiling, and answered 29.99929539, just like the Canvas calculator said. I would like to deduct 1 point for them. And I don't want to do this manually for a class of 200 students.

Thanks much for any help.
