Undefined is a term used when a mathematical result has no meaning. More precisely, undefined values occur when an expression is evaluated for input values outside of its domain. ( 1 if no complex numbers) ( 2 if no complex numbers) ( units in radians, no complex infinity)
1 If both the base and the exponent are zero (or are evaluated to zero), the result is Float(undefined) if the exponent is the float 0.0; with an integer as exponent, the evaluation of 0 0 results in the integer 1, while that of 0. 2  0 results in the float 1.0.
