Combinations & s
The calculator computes the number of combinations of
n items taken r at a
time. Both the n and r variables must be greater than 0.
Permutations & m
The calculator computes the number of permutations of
n items taken r at a
time. Both the n and r variables must be greater than 0.
Rounding & o
The calculator computes using the rounded, displayed form of a number
instead of the internally stored value.
For example, working in the Bond worksheet, you might want to round a
computed selling price to the nearest penny (two decimal places) before
continuing your calculation.
Note: The calculator stores values to an accuracy of up to 13 digits. The
decimal format setting rounds the displayed value but not the unrounded,
internally stored value. (See “Choosing the Number of Decimal Places
Displayed”.)
