Degrees-to-Radians-to-Degrees: Conversion between Radians and Degrees

Description

Converts radians to degrees and vice versa.

Usage

deg2rad(d)
rad2deg(r)

Arguments

d

degrees

r

radians

encoding

UTF-8

Details

Since $\pi\,\mathrm{rad}=180^{\circ}$, degrees ($d$) can be converted to radians ($r$) using $r=d\cdot{}\pi/180$ and the conversion of radians to degrees is $d=r\cdot{}180/\pi$.
