/**
|
|
* Returns a ratio that can be used to interpolate between exponential function
|
|
* stops.
|
|
* How it works: Two consecutive stop values define a (scaled and shifted) exponential function `f(x) = a * base^x + b`, where `base` is the user-specified base,
|
|
* and `a` and `b` are constants affording sufficient degrees of freedom to fit
|
|
* the function to the given stops.
|
|
*
|
|
* Here's a bit of algebra that lets us compute `f(x)` directly from the stop
|
|
* values without explicitly solving for `a` and `b`:
|
|
*
|
|
* First stop value: `f(x0) = y0 = a * base^x0 + b`
|
|
* Second stop value: `f(x1) = y1 = a * base^x1 + b`
|
|
* => `y1 - y0 = a(base^x1 - base^x0)`
|
|
* => `a = (y1 - y0)/(base^x1 - base^x0)`
|
|
*
|
|
* Desired value: `f(x) = y = a * base^x + b`
|
|
* => `f(x) = y0 + a * (base^x - base^x0)`
|
|
*
|
|
* From the above, we can replace the `a` in `a * (base^x - base^x0)` and do a
|
|
* little algebra:
|
|
* ```
|
|
* a * (base^x - base^x0) = (y1 - y0)/(base^x1 - base^x0) * (base^x - base^x0)
|
|
* = (y1 - y0) * (base^x - base^x0) / (base^x1 - base^x0)
|
|
* ```
|
|
*
|
|
* If we let `(base^x - base^x0) / (base^x1 base^x0)`, then we have
|
|
* `f(x) = y0 + (y1 - y0) * ratio`. In other words, `ratio` may be treated as
|
|
* an interpolation factor between the two stops' output values.
|
|
*
|
|
* (Note: a slightly different form for `ratio`,
|
|
* `(base^(x-x0) - 1) / (base^(x1-x0) - 1) `, is equivalent, but requires fewer
|
|
* expensive `Math.pow()` operations.)

/**

* Special form for comparison operators, implementing the signatures:
|
|
* - (T, T, ?Collator) => boolean
|
|
* - (T, value, ?Collator) => boolean
|
|
* - (value, T, ?Collator) => boolean
|
|
*
|
|
* For inequalities, T must be either value, string, or number. For ==/!=, it
|
|
* can also be boolean or null.
|
|
*
|
|
* Equality semantics are equivalent to Javascript's strict equality (===/!==)
|
|
* -- i.e., when the arguments' types don't match, == evaluates to false, != to
|
|
* true.
|
|
*
|
|
* When types don't match in an ordering comparison, a runtime error is thrown.
