(expt x) is equivalent to (expt x 1); and yields x for all x. -For three or more arguments, the operation is left associative. -That is to say, (expt x y z) is equivalent to (expt (expt x y) z) and -so forth. Exponentiation is done pairwise using a binary operation. +For three or more arguments, the operation is right associative. +That is to say, (expt x y z) is equivalent to (expt x (expt y z)) and +so forth, similarly to the way nested exponents work in standard algebraic +notation. + +Exponentiation is done pairwise using a binary operation. If both operands to this binary operation are integers, then the result is an integer. If either operand is a float, then the other operand is converted to a float, and a floating point exponentation |
