Jakob: Yes, it is base 10, but the dividers are not located at exact power of 10 due to the specified upper bound and the number of dividers.
Here's how the divider locations get calculated: log_10(upperBound) = log_10(2000) = 3.301029996 log_10(lowerBound) = 0 The dividers are evenly spaced between [0 .. 3.301029996]: 10^0 = 1 10^0.660205999 = 5 10^1.320411998 = 21 10^1.980617997 = 96 10^2.640823997 = 437 10^3.301029996 = 2000 To make the dividers evenly spaced, you need to use an upper bound that is a multiple of 10 and then use log_10 of the upper bound + 1 as the number of dividers. For example, when the upper bound 100000 and the number of dividers 6, you will get the dividers at exact power of 10.
