in reply to zero to the power zero
From all my math, 00 is not defined. See, for example, "The definition 0^0==1 is sometimes used to simplify formulas, but it should be kept in mind that this equality is a definition and not a fundamental mathematical truth (Knuth 1992; Knuth 1997, p. 56)." from MathWorld. Also, according to here, 00 is undefined. As to why, see here.
00 = 1 is incorrect. Perl should give NaN for 0**0.
