Special methods for numeric types

__add__(self, other)

join

__sub__(self, other)

join

__mul__(self, other)

join

__div__(self, other)

join

__mod__(self, other)

join

__divmod__(self, other)

join

__pow__(self, other)

join

__lshift__(self, other)

join

__rshift__(self, other)

join

__and__(self, other)

join

__xor__(self, other)

join

__or__(self, other)

break Called to implement the binary arithmetic operations (+, -, *, /, %, divmod(), pow(), <<, >>, &, ^, |).

__neg__(self)

join

__pos__(self)

join

__abs__(self)

join

__invert__(self)

break Called to implement the unary arithmetic operations (-, +, abs() and ~).

__nonzero__(self)

Called to implement boolean testing; should return 0 or 1. An alternative name for this method is __len__.

__coerce__(self, other)

Called to implement ``mixed-mode'' numeric arithmetic. Should either return a tuple containing self and other converted to a common numeric type, or None if no way of conversion is known. When the common type would be the type of other, it is sufficient to return None, since the interpreter will also ask the other object to attempt a coercion (but sometimes, if the implementation of the other type cannot be changed, it is useful to do the conversion to the other type here).

Note that this method is not called to coerce the arguments to + and *, because these are also used to implement sequence concatenation and repetition, respectively. Also note that, for the same reason, in n*x, where n is a built-in number and x is an instance, a call to x.__mul__(n) is made.

__int__(self)

join

__long__(self)

join

__float__(self)

break Called to implement the built-in functions int(), long() and float(). Should return a value of the appropriate type.

__oct__(self)

join

__hex__(self)

break Called to implement the built-in functions oct() and hex(). Should return a string value.
