Methods
- distribution() : array<string|int, mixed>|float|string
- F.DIST.
- evaluateArrayArguments() : array<string|int, mixed>
- Handles array argument processing when the function accepts multiple arguments, and any of them can be an array argument.
- evaluateArrayArgumentsIgnore() : array<string|int, mixed>
- Handles array argument processing when the function accepts multiple arguments, and any of them can be an array argument except for the one specified by ignore.
- evaluateArrayArgumentsSubset() : array<string|int, mixed>
- Handles array argument processing when the function accepts multiple arguments, but only the first few (up to limit) can be an array arguments.
- evaluateArrayArgumentsSubsetFrom() : array<string|int, mixed>
- Handles array argument processing when the function accepts multiple arguments, but only the last few (from start) can be an array arguments.
- evaluateSingleArgumentArray() : array<string|int, mixed>

Methods
distribution()
F.DIST.
public
static distribution(mixed $value, mixed $u, mixed $v, mixed $cumulative) : array<string|int, mixed>|float|string
Returns the F probability distribution. You can use this function to determine whether two data sets have different degrees of diversity. For example, you can examine the test scores of men and women entering high school, and determine if the variability in the females is different from that found in the males.
Parameters
- $value : mixed
-
Float value for which we want the probability Or can be an array of values
- $u : mixed
-
The numerator degrees of freedom as an integer Or can be an array of values
- $v : mixed
-
The denominator degrees of freedom as an integer Or can be an array of values
- $cumulative : mixed
-
Boolean value indicating if we want the cdf (true) or the pdf (false) Or can be an array of values
Return values
array<string|int, mixed>|float|string —If an array of numbers is passed as an argument, then the returned result will also be an array with the same dimensions
evaluateArrayArguments()
Handles array argument processing when the function accepts multiple arguments, and any of them can be an array argument.
protected
static evaluateArrayArguments(callable $method, mixed ...$arguments) : array<string|int, mixed>
Example use for: ROUND() or DATE().
Parameters
- $method : callable
- $arguments : mixed
Return values
array<string|int, mixed>evaluateArrayArgumentsIgnore()
Handles array argument processing when the function accepts multiple arguments, and any of them can be an array argument except for the one specified by ignore.
protected
static evaluateArrayArgumentsIgnore(callable $method, int $ignore, mixed ...$arguments) : array<string|int, mixed>
Example use for: HLOOKUP() and VLOOKUP(), where argument 1 is a matrix that needs to be treated as a database rather than as an array argument.
Parameters
- $method : callable
- $ignore : int
- $arguments : mixed
Return values
array<string|int, mixed>evaluateArrayArgumentsSubset()
Handles array argument processing when the function accepts multiple arguments, but only the first few (up to limit) can be an array arguments.
protected
static evaluateArrayArgumentsSubset(callable $method, int $limit, mixed ...$arguments) : array<string|int, mixed>
Example use for: NETWORKDAYS() or CONCATENATE(), where the last argument is a matrix (or a series of values) that need to be treated as a such rather than as an array arguments.
Parameters
- $method : callable
- $limit : int
- $arguments : mixed
Return values
array<string|int, mixed>evaluateArrayArgumentsSubsetFrom()
Handles array argument processing when the function accepts multiple arguments, but only the last few (from start) can be an array arguments.
protected
static evaluateArrayArgumentsSubsetFrom(callable $method, int $start, mixed ...$arguments) : array<string|int, mixed>
Example use for: Z.TEST() or INDEX(), where the first argument 1 is a matrix that needs to be treated as a dataset rather than as an array argument.
Parameters
- $method : callable
- $start : int
- $arguments : mixed
Return values
array<string|int, mixed>evaluateSingleArgumentArray()
Handles array argument processing when the function accepts a single argument that can be an array argument.
protected
static evaluateSingleArgumentArray(callable $method, array<string|int, mixed> $values) : array<string|int, mixed>
Example use for: DAYOFMONTH() or FACT().
Parameters
- $method : callable
- $values : array<string|int, mixed>
Return values
array<string|int, mixed>initialiseHelper()
private
static initialiseHelper(array<string|int, mixed>|false $arguments) : void
Parameters
- $arguments : array<string|int, mixed>|false
-
Can be changed to array for Php8.1+
testFalse()
private
static testFalse(mixed $value) : bool
Parameters
- $value : mixed
