test(CL): math package tests at low price level

[p0mvn]

Background

Given the bug in #6351, it might be prudent to unit test our internal functions at a lower price level more extensively than it is right now.

Suggested Design

Review every function in the math package. Where applicable, add a test case at a lower price level (near min tick bound). Try to reason about cases where rounding errors can be amplified

Acceptance Criteria

• Reviewed each function
• Tests around min spot price added
• Reason about error amplification
