			# Objective - Fixes #15236 ## Solution - Use bevy_math::ops instead of std floating point operations. ## Testing - Did you test these changes? If so, how? Unit tests and `cargo run -p ci -- test` - How can other people (reviewers) test your changes? Is there anything specific they need to know? Execute `cargo run -p ci -- test` on Windows. - If relevant, what platforms did you test these changes on, and are there any important ones you can't test? Windows ## Migration Guide - Not a breaking change - Projects should use bevy math where applicable --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com> Co-authored-by: IQuick 143 <IQuick143cz@gmail.com> Co-authored-by: Joona Aalto <jondolf.dev@gmail.com>
