Spreadsheet Formulas - Numeric Functions
Statistica provides a predefined broad selection of numeric and logical functions that can be used in spreadsheet formulas like all other functions.
Below is a list of numeric and logical spreadsheet functions (parameters are given in parentheses).
| Floor(number) | Returns the largest integer less than or equal to its argument. For example:
Floor(2.7) results in 2, but Floor(-0.5) results in 1 |
| Ceiling(number) | Returns the smallest integer greater than or equal to its argument. For example:
Ceiling(2.3) results in 3 Ceiling(-2.3) results in -2 |
| Round(number, dec) | Rounds the first argument to the number of decimal places given by the second argument. For example:
Round(3.554, 2) rounds to 3.55 Round(3.555, 2) rounds to 3.56 Round(4.5, 0) rounds to 5* |
| FACT(number) | Truncates its numeric argument to an integer and returns the factorial of this integer. |
| COMBIN(n, k) | Returns the number of combinations of n things taken k at a time, n!/k!(n - k)! |
| PERMUT(n, k) | Returns the number of permutations of n items taken k at a time, n!/(n - k)! |
| CHOOSE(i, V1, V2, …, Vn) | Returns the ith value, Vi. This function accepts arguments as numeric or text. |
| MATCH(value, V1, R1, V2, R2, …, Vn, Rn [, Rdefault]) | If value = Vi, returns Ri, or returns Rdefault (if specified). Otherwise, returns missing data. |
| IN(val, list-val1, [list-val2, list-val3, …]) | Returns a non-zero value (true) if the first argument is equal to any of the remaining arguments. All arguments may be constants, variable references, or expressions and works with text or numbers. |
*Round(4.5, 0) in a Statistica spreadsheet or in Excel yields 5 (Arithmetic rounding); in Statistica Visual Basic or Visual Basic, this formula yields 4 (Banker's rounding, that is, rounds .5 either up or down, whichever results in an even number).
