The arithmetic operations in Pi/Pie are the same as Python.
x = 3 y = 2 a = x + y b = x - y m = x * y p = x**y d = x / y r = x % y
** means the power operator so p is 9. % is the modulo operator so r is 1.
Operator as function
This section will be changed in the future. The plus operator (+) is the special form of __add__ function of number class N, Z, Q, R, C. So 1 + 2 is equal to:
1.__add__(2)
But Pi/Pie IDE should not support this confusing expression.
The power operator is formally equal to __power__ function and the argument type of it is Z. So
3**0.6
is invalid. Whether an operator is valid or not is judged by the argument type of operator function.
Support of operations like +=
I will not support += like operations in Pi/Pie.
