# FINV

Spread for WinForms provides advanced software components that support Excel import/export, full cell customization, an extensive calculation engine with over 450 functions and more, all with zero dependencies on Excel.

## Content



This function returns the inverse of the F probability distribution.

## Syntax

FINV(*p*,*degnum*,*degden*)

## Arguments

This function has these arguments:

| **Argument** | **Description** |
| -------- | ----------- |
| *p* | Probability associated with the F cumulative distribution |
| *degnum* | Number of degrees of freedom for the numerator; if not an integer, the number is truncated |
| *degden* | Number of degrees of freedom for the denominator; if not an integer, the number is truncated |

If either *degnum* or *degden* is not an integer, it is truncated.

## Remarks

This function calculates the inverse of the F probability distribution, so if p = FDIST(x,...), then FINV(p,...) = x.

## Data Types

Accepts numeric data for all arguments. Returns numeric data.

## Examples

`FINV(A1,2,2)`
`FINV(R1C1,2,1)`
`FINV(0.021,5,3)` gives the result 16.83975

## Version Available

This function is available in product version 1.0 or later.
