# FunctionSpaceReduce(R, F)¶

bringDown(f, k) is like bringDown(f) but k is algebraic kernel and the result is reduced modulo minimal polynomial of k.
bringDown(f) replaces transcendental kernels in f by random integers. Error if f contains algebraic kernel.
newReduc(n) empties reduction state. n is size of random integers to use during next reduction.
