Returns the ith segment of length number of exponential segments whose values sum to sum. The exponential curve is defind by power, where 0<power<1 yields concave slopes and power>1 yields convex slopes. The type of the value returned normally depends on the type of the arguments specified to the function. Use :return-type to force the return value to be either float, integer or ratio. float may be specified as a list (float digits) in which case the floating point return value will be rounded to digitnumber of places.
