◆ DELTA()

static PHPExcel_Calculation_Engineering::DELTA	(	$a,

DELTA.

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.

Excel Function: DELTA(a[,b])

Parameters

float	$a	The first number.
float	$b	The second number. If omitted, b is assumed to be zero.

Returns: int

◆ ERF()

static PHPExcel_Calculation_Engineering::ERF	(	$lower,

ERF.

Returns the error function integrated between the lower and upper bound arguments.

Note: In Excel 2007 or earlier, if you input a negative value for the upper or lower bound arguments, the function would return a #NUM! error. However, in Excel 2010, the function algorithm was improved, so that it can now calculate the function for both positive and negative ranges. PHPExcel follows Excel 2010 behaviour, and accepts nagative arguments.

Excel Function: ERF(lower[,upper])

Parameters

float	$lower	lower bound for integrating ERF
float	$upper	upper bound for integrating ERF. If omitted, ERF integrates between zero and lower_limit

Returns: float
