hsluvToRgb returns negative values for saturation 100

[vorg]

For saturation 100 quite often I get RGB results with one of the components slightly below zero:

hsluv.hsluvToRgb([171, 100, 55])
//[-3.261485526095953e-13, 0.5825533896631454, 0.5048262083306216]

I've noticed that while working on my HSLuv color picker. As i convert hsluv to float RGB and then back to hex using pex-color/index.js#L305. If I use your hsluv.hsluvToHex it works correctly.

Wrong:

Thank you for the report. The fix is really easy in code, but I have to look into floating point error first, not sure what's best practices are.
