Calcpad version 5.8.1.

[Proektsoftbg]

A consistent system of native angle units was inmplemented:
° or deg - degrees;
′ - minutes
″ - seconds;
rad - radians;
grad - gradians (grades);
You can use them as arguments of trigonometric functions, do arithmetic operations or convert between them as other units:

Operator precedence bug for multiplication with units was fixed. In previous versions 1/2m was treated in the same way as 1/2m = 1/(2m) = 0.5m^(-1). Now, 1/2m = 0.5m as expected.
Fixed unsaved input values bug for included files. When all input fields were into the included files, they were not saved in the file.
Quick help was updated with the new features - macros, includes and angle units.

Yes, this behavior is much more reliable than it was in 5.8. I haven't found any traps yet.

The addition of angle units is much appreciated. It would be great to add "rev" as an angle unit. It would allow to convert rpm "rev/min" to "rad/s" easily for example.

Good sugestion, thank you!

Rev units are implemented in v.5.8.3, #48.

However, the old unit rpm is now not compatible to rev/min, because it is reduced to min^-1, just as as 1Hz = 1s^-1. We will think later how to resolve this. I do not want to change existing uints, because it will affect all existing worksheets, that uses them. Probably, we need (angle) version of these units, e.g. ∡rpm = 1rev/min.
