Description

The A→∡r command turns a scalar or a suitable component of a composite object into an angle measured in radians.

In particular, if the component is:

  • a scalar, then the number is interpreted as an angle in the current angular mode and converted to radians;
  • a polar complex number, then the angular component is converted to radians;
  • an angle, then the angle is converted to radians;
  • a vector, then any angle or polar complex number but not scalars is converted to radians as per above rules.

Compatibility

A→∡r is specific to newRPL and has no direct equivalent in userRPL.
