Permutation (nPr) and Combination (nCr)

These functions make it possible to perform permutation and combination calculations. n and r must be integers in the range of 0 ≤ r ≤ n < 1 ✕ 1010.

How many four-person permutations and combinations are possible for a group of 10 people?

Rounding Function (Rnd)

This function rounds the value or the result of the expression in the function’s argument to the number of significant digits specified by the number of display digits setting.

Display Digits Setting: Norm1 or Norm2

The mantissa is rounded to 10 digits.

Display Digits Setting: Fix or Sci

The value is rounded to the specified number of digits. Example: 200 ÷ 7 ✕ 14 = 400
