Conversions

Conversions between Degrees and Radians

Convert the given angle (degrees) to radians. 

let radians = degToRad(90) // PI / 2 radians

Convert the given angle (radians) to degrees. 

let degrees = radToDeg(Math.PI / 2) // 90 degrees

Conversions of Radius to Segments

Calculate the number of segments from the given radius based on minimum length or angle.

There are various round shapes that support the 'segments' option. Often times, a design requires a specific precision for each segment. This function assists by calculating the appropriate number of segments based on radius, as well as minimum length or minimum angle. 

let segments = radiusToSegments(3.5, 0.1, 0) /* use minimum length */
let segments = radiusToSegments(3.5, 0, Math.PI * 2 / 300) /* use minimum angle */
