I wanted to use a power function for some procedural generation, but also needed to preserve the sign of the input and not be limited to uneven integer exponents. This seems like a basic enough use that I am surprised that I could not find a specific term for the function. Also, is there any simple alternative with similar properties?

Is there a term for the function $\operatorname{sign}(x) \times |x|^a$?
