5.9.2 Usual infixed functions on reals : +,,*,/,^
+,,*,/,^ are the usual operators to do
additions, subtractions, multiplications, divisions and for raising to a
power.

Remark
You may use the square key or the cube key if your keyboard has one,
for example : 3^{2} returns 9.
Remark on non integral powers

If x is not an integer, then a^{x}=exp(x ln(a)), hence
a^{x} is welldefined only for a>0 if x is not rational. If x
is rational and a<0, the principal determination of the logarithm
is used, leading to a complex number.
 Hence be aware of the difference between (a)^{1/n} and a^{1/n}
when n is an odd integer.
For example, to draw the graph of y=∛x^{3}−x^{2}, input :
plotfunc(ifte(x>0,(x^
3x^
2)^
(1/3),
(x^
2x^
3)^
(1/3)),x,xstep=0.01)
You might also input :
plotimplicit(y^
3=x^
3x^
2)
but this is much slower and much less accurate.
