log-scale

log-scale is a logarithmic scale class that helps with conversions and calculations.

Usage

Create a LogScale by passing in your min and max values:

var logScale = new LogScale(1, 100);

You can then convert from a 0 to 1 linear scale and the logarithmic scale and vice versa. For example, if you want the value at the middle of the scale:

logScale.linearToLogarithmic(.5); // 10

And going the other way:

logScale.logarithmicToLinear(1); // 0
logScale.logarithmicToLinear(10); // .5
logScale.logarithmicToLinear(100); // 1

Testing

You can run the tests with the following command:

jasmine
