Here's a simple example:
{{{
sage: a = real((-I*float(1))^2); a
-1.00000000000000
sage: float(a)
Traceback (most recent call last):
...
TypeError: can't convert complex to float; use abs(z)
sage: b = a.simplify(); b
-1.0
sage: float(b)
-1.0
}}}
Dylan Thurston reported this on sage-support, but in a more complicated
situation involving plotting.
