@code_typed: positiveReal^realExponent

Hi, using @code_typed in the code below, shows that julia checks for the sign of a number X when raised to the power of a real number (pow function). is it possible to avoid this if X is positive X=abs(…)?
code:
cTime+(abs(q[i]/df))^(1/3)

In general, the compiler can’t specialize on the value of the function, only the type…

However, in the particular case of x^(1/3) you should call the cbrt function rather than using generic exponentiation.
