Negative Steps return Step 1

[Sam Richard]

When using Modular Scale 2.0.0.alpha5, I call the following function:

ms(1, 100, 1.618);
ms(-1, 100, 1.618);
ms(2, 100, 1.618);

The first two items return the same number, that being the ratio. The third produces a different number. Having tested this, any negative number will produce the same result as step 1.

Can you tell me what your output is? I am unable to replicate this.

@debug ms(2, 100, 1.618);
@debug ms(1, 100, 1.618);
@debug ms(0, 100, 1.618);
@debug ms(-1, 100, 1.618);
@debug ms(-2, 100, 1.618);
@debug ms(-3, 100, 1.618);

I'm working on Singularity Extras and trying to debug the ratio-spiral issue (returns a string instead of a list of numbers) and am using the Compass version of Modular Scale (so the Ruby functions). Maybe the problem's in the Ruby functions, not the Sass functions?
