Here is the question in Russian Forum regarding roots extracting.
In Caché ObjectScript we use exponentiation operator (**) to raise an exponent to power. F.e. let's raise 3 to power of 3:
USER> write 3**3 27
And we use the same operator to extract the root.
USER> write 27**(1/3) 2.999999999999999963
And 2.999999999999999963 is not 3, obviously.
How to extract roots properly in Caché ObjectScript?
