This member function initializes the invoking function as a step function that repeats the step function f, n times after x0. More precisely, if f is defined on [xfpMin,xfpMax) and if the invoking function is defined on [xMin,xMax), the value of the invoking function will be:

• dval on [xMin, x0),
• fp((x-x0) % (xfpMax-xfpMin)) for x in [x0, Min(x0+n///(xfpMax-xfpMin), xMax)), and
• dval on [Min(x0+n///(xfpMax-xfpMin), xMax), xMax)

This member function sets the value of the invoking step function to be v on the interval [x1, x2).
