I found the infix operator names (^^) and (**) not very intuitive and defined (^-) and (^/) in NumericPrelude, in order to show, that the first one allows negative exponents and the second one allows fractional exponents. Unfortunately the first one looks like power function with negated exponent and I had no better idea for an identifier so far.
Ah, so x ^- 2 (or is it x ^- 2.0) is not the square root of x? Maybe you should change this identifier indeed!
If at all, it could be misinterpreted as 1/x^2. Square root would be x^/0.5.
Maybe use ^+- instead.
Nice idea! Analogously I could define (^*/).
