    sinusoidal-decimal

    This is a lightweight way to apply a sine curve to numbers in a numeric range.

    It is similar to easing, but intended for cases where you have a numeric start point, end point, and position(s) relative to these points.

    const sinusoidal = require('sinusoidal-decimal')
     
    // Usage: sinusoidal(value, min, max, returnDecimal)
     
    sinusoidal(0, 10, 50) // 10
    sinusoidal(10, 10, 50) // 10
    sinusoidal(20, 10, 50) // 15.8578...
    sinusoidal(30, 10, 50) // 30
    sinusoidal(40, 10, 50) // 44.1421...
    sinusoidal(50, 10, 50) // 50
    sinusoidal(60, 10, 50) // 50
     
    // If returnDecimal flag is true, returns decimal position on sine curve
     
    sinusoidal(0, 10, 50, true) // 0
    sinusoidal(10, 10, 50, true) // 0
    sinusoidal(20, 10, 50, true) // 0.1464...
    sinusoidal(30, 10, 50, true) // 0.5
    sinusoidal(40, 10, 50, true) // 0.8535...
    sinusoidal(50, 10, 50, true) // 1
    sinusoidal(60, 10, 50, true) // 1
