Re: [Gcalc-devel] Y = X^(3/5) does not graph correctly

[Mike A. <ar...@gr...>]

Marvin,
    Thanks for the notice.  While x^(3/5) does indeed have a domain that
includes negative numbers, neither GraphCalc, nor any other graphing
calculator I know, graphs this region.  This is due to the fact that
(3/5) is evaluated first and transformed into a decimal that is very
very close 0.6 (but not exactly).  And while x^0.6 does exist, x^(very
very close to 0.6) does not.
