5.2 work2 documentation for math.pow

["Liam Devine" <liamdevine@...>]

The work documentation for math.pow still states [1]:
"Returns xy. (You can also use the expression x^y to compute this value.) "

This is not always true and depends on the operands:

lua53 -e"print(math.pow(2,-1))"
0.5

lua53 -e"print(2.^-1)"
0.5

lua53 -e"print(2^-1)"
lua53: (command line):1: integer exponentiation with negative exponent
stack traceback:
	(command line):1: in main chunk
	[C]: in ?
