Parameters

args:ValueEval[]

the pre-evaluated arguments for this function. args is never null, nor are any of its elements.

isDefaultResult	back to summary
private static boolean isDefaultResult(double x, double mean) This checks is x = 0 and the mean = 0. Excel currently returns the value 1 where as the maths common implementation will error. Parameters x:double The number. mean:double The mean. Returns:boolean If a default value should be returned.

isDefaultResult

private static boolean isDefaultResult(double x, double mean)

This checks is x = 0 and the mean = 0. Excel currently returns the value 1 where as the maths common implementation will error.

Parameters

Returns:boolean

If a default value should be returned.
