Squaring of zero value returns wrong result

[Former user]

Try to square an expression that evaluates to zero, in the most simple case (0)^2. The result should be well defined (=0), but SpeedCrunch 0.12 returns NaN.

The original expression where I encountered this error was sqrt(((0*pi/(96e-3))^2)) which results in "undefined argument domain". It would be helpful if NaN would appear there somewhere since this error was kind of misleading. Thanks

Running in latest development master code:

(0)^2
= 0

(0*pi/(96e-3))^2
= 0

sqrt(((0*pi/(96e-3))^2))
= 0

Whatever was broken in 0.12, seems to be fixed now. @tey @polwel Do you guys remember this issue from before?
