$initializationNeeded

private static bool $initializationNeeded = true

Methods

BESSELY()

BESSELY.

public static BESSELY(mixed $x, mixed $ord) : array<string|int, mixed>|float|string

Returns the Bessel function, which is also called the Weber function or the Neumann function.

Excel Function: BESSELY(x,ord)

Parameters
$x : mixed

A float value at which to evaluate the function. If x is nonnumeric, BESSELY returns the #VALUE! error value. Or can be an array of values

$ord : mixed

The integer order of the Bessel function. If ord is not an integer, it is truncated. If $ord is nonnumeric, BESSELY returns the #VALUE! error value. If $ord < 0, BESSELY returns the #NUM! error value. Or can be an array of values

Return values
array<string|int, mixed>|float|string —

Result, or a string containing an error 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>

testFalse()

private static testFalse(mixed $value) : bool
Parameters
$value : mixed
Return values
bool
