This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mumath) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

API
round(value, step?)
Rounds value to optional step
.
round(0.3, .5)
→ .5
len(a, b)
Return length of a vector.
precision(value)
Get precision from float:
1.1 → 1, 1234 → 0, .1234 → 4
clamp(value, left, right)
Return value clamped by left/right limits (or vice-versa).
lerp(x, y, ratio)
Return value interpolated between x and y.
within(value, left, right)
Whether element is between left & right, including.
mod(value, min?, max)
An enhanced mod-loop — loops value within a frame.
closest(value, list)
Get closest value out of a set.
scale(value, list)
Get first scale out of a list of basic scales, aligned to the power. E. g.
step(.37, [1, 2, 5])
→ .5
step(456, [1, 2])
→ 1000
Similar to closest, but takes all possible powers of scales.
order(value)
Get order of magnitude for a number.
order(123) → 100; order(-0.0003) → 0.0001;
isMultiple(a, b, eps?)
Same as a % b === 0
, but with precision check.
