Find out the number of decimal places in a number.

Original implementation from https://stackoverflow.com/questions/5173692/how-to-return-number-of-decimal-places-in-r

decimalplaces(x, true_number = FALSE)

Arguments

x	Float or double numeric number.
true_number	Logical setting whether the true number (see notes) of decimal places.

Value

Note

R usually restricts the number of decimal to 9 in printing etc. Unless true_number = TRUE, return 9 and give a warning.
