Conversions and calculations on a logarithmic scale
npm install log-scalelog-scale is a logarithmic scale class that helps with conversions and calculations.
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
You can run the tests with the following command:
jasmine
