Methods

• classmethod %EvaluateScalar(pFunc As %String, pValue1 As %String = "", pValue2 As %String = "", pValue3 As %String = "", pValue4 As %String = "") as %String

Evaluate the given scalar function, pFunc, and return the result.

• classmethod %IsScalarFunction(pFunc As %String) as %String

Test if pFunc is a scalar function. Return -1 if function is not a scalar function, otherwise return the number of arguments and (total number of) optional arguments (args:optargs) expected by the function.

• classmethod ISNULL(pValue As %Double, pReplacement As %Double) as %Double

IsNull scalar function: If value is "", return replacment,

• classmethod LOG(pValue As %Double) as %Double

Log base 10 scalar function.

• classmethod LOOKUP(pTermList As %String, pKey As %String, pDefault As %String = "", pField As %String = "") as %String

Lookup a value in a term list.

• classmethod POWER(pValue As %Double, pArg As %Double) as %Double

Power scalar function.

• classmethod ROUND(pValue As %Double, pDigits As %Integer = 0) as %Double

Round the given value to pDigits places.

• classmethod SQRT(pValue As %Double) as %Double

Square root scalar function.
