Methods
DELTA()
DELTA.
public
static DELTA(array<string|int, mixed>|bool|float|int|string $a[, array<string|int, mixed>|bool|float|int|string $b = 0.0 ]) : array<string|int, mixed>|int|string
Excel Function: DELTA(a[,b])
Tests whether two values are equal. Returns 1 if number1 = number2; returns 0 otherwise. Use this function to filter a set of values. For example, by summing several DELTA functions you calculate the count of equal pairs. This function is also known as the Kronecker Delta function.
Parameters
- $a : array<string|int, mixed>|bool|float|int|string
-
the first number Or can be an array of values
- $b : array<string|int, mixed>|bool|float|int|string = 0.0
-
The second number. If omitted, b is assumed to be zero. Or can be an array of values
Return values
array<string|int, mixed>|int|string —(string in the event of 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
GESTEP()
GESTEP.
public
static GESTEP(array<string|int, mixed>|bool|float|int|string $number[, null|array<string|int, mixed>|bool|float|int|string $step = 0.0 ]) : array<string|int, mixed>|int|string
Excel Function: GESTEP(number[,step])
Returns 1 if number >= step; returns 0 (zero) otherwise Use this function to filter a set of values. For example, by summing several GESTEP functions you calculate the count of values that exceed a threshold.
Parameters
- $number : array<string|int, mixed>|bool|float|int|string
-
the value to test against step Or can be an array of values
- $step : null|array<string|int, mixed>|bool|float|int|string = 0.0
-
The threshold value. If you omit a value for step, GESTEP uses zero. Or can be an array of values
Return values
array<string|int, mixed>|int|string —(string in the event of 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
