$initializationNeeded

private static bool $initializationNeeded = true

Methods

base10()

LOG10.

public static base10(mixed $number) : array<string|int, mixed>|float|string

Returns the result of builtin function log after validating args.

Parameters
$number : mixed

Should be numeric Or can be an array of values

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

Rounded number If an array of numbers is passed as an argument, then the returned result will also be an array with the same dimensions

natural()

LN.

public static natural(mixed $number) : array<string|int, mixed>|float|string

Returns the result of builtin function log after validating args.

Parameters
$number : mixed

Should be numeric Or can be an array of values

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

Rounded number If an array of numbers is passed as an argument, then the returned result will also be an array with the same dimensions

withBase()

LOG_BASE.

public static withBase(mixed $number[, mixed $base = 10 ]) : array<string|int, mixed>|float|string

Returns the logarithm of a number to a specified base. The default base is 10.

Excel Function: LOG(number[,base])

Parameters
$number : mixed

The positive real number for which you want the logarithm Or can be an array of values

$base : mixed = 10

The base of the logarithm. If base is omitted, it is assumed to be 10. Or can be an array of values

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

The 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>

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
Return values
bool
