Support floating-point base in FURB163 (#9100)

## Summary

<!-- What's the purpose of the change? What does it do, and why? -->

Check floating-point numbers similarly to integers in FURB163. For
example, both `math.log(x, 10)` and `math.log(x, 10.0)` should be
changed to `math.log10(x)`.

## Test Plan

<!-- How was it tested? -->

Added couple of test cases.
