angle

class guppylang.std.angles.angle

Not an angle in the truest sense but a rotation by a number of half-turns (does not wrap or identify with itself modulo any number of complete turns).

The halfturns field stores the number of half-turns, and float() converts to radians by multiplying by π. The built-in constant pi equals angle(1).

For example, angle(1/2) is equivalent to pi / 2:

angle(1/2) == pi / 2   # True: both represent π/2 radians (90°)
angle(1)   == pi       # True: both represent π radians (180°)
angle(2)   == angle(0) # False: a full turn is not identified with zero

__add__(other: angle) → angle

__eq__(other: angle) → bool

Return self==value.
