The value is treated as radians regardless of mode. It returns the value for use in sin( and related commands.

If the mode is Radian, it multiplies value by 1. If the mode is Degree, it multiplies value by 180/pi.



  • 2ND + APPS (ANGLE)
  • 3:r


  • 2ND + 5 (MATH)
  • 2:Angle
  • 2:r


:Disp "π/2r",π/2r
:Disp "π/4r",π/4r

This converts several radian values to Degrees.
