5// More angle units on top of the built-in deg (also written °) and rad:
6// gradians, arcminutes and arcseconds. Like deg and rad they work in
7// sin()/cos()/tan() and convert with "in": sin(100 grad) is 1,
8// 1 deg in arcmin is 60 arcmin.

10defunit("grad", 0.9, "deg") // gradian: 400 grad = 360 deg
11defunit("arcmin", 1 / 60, "deg") // arcminute: 60 arcmin = 1 deg
12defunit("arcsec", 1 / 3600, "deg") // arcsecond: 3600 arcsec = 1 deg
