Bug in snap utility

[Taylan]

E.g. gsap.utils.snap(0.05, -0.16) returns -0.16 instead of -0.15.

 

Probably caused by combination of negative & floating point numbers.

Another probably related situation where it doesn't snap exactly:

gsap.utils.snap(-0.05, -0.13) // -0.151 instead of -0.15

Thanks for reporting this, Taylan. We'll get it fixed in the next version.

This should be resolved in the next release which you an preview at https://assets.codepen.io/16327/gsap-latest-beta.min.js

 

FYI, it has to do with tiny imprecisions in JavaScript math (floating point, as you mentioned) and the fact that Math.floor() works in the opposite direction for negative values. Like Math.floor(-150.00000000000003) is 151 instead of -150. 😐

 

Sorry about any confusion there.
