Decimal Place =

log(x)/ln(x) Option for Geometric mean =

Last code change on 02.04.2023,
You can also input x and cf values. Calculator will first generate x and f table and then Mean, Median, etc...
For wrong solution or incomplete solution or GUI improvement, please submit the feedback form. So, I will try my best to improve it soon.
