org.apache.poi.ss.formula.functions.Oct2Dec

All Implemented Interfaces:

FreeRefFunction, Function, Function1Arg

public class Oct2Dec
extends Fixed1ArgFunction
implements FreeRefFunction

Implementation for Excel Oct2Dec() function.

Converts an octal number to decimal.

Syntax:
Oct2Dec (number )

Number is the octal number you want to convert. Number may not contain more than 10 octal characters (30 bits). The most significant bit of number is the sign bit. The remaining 29 bits are magnitude bits. Negative numbers are represented using two's-complement notation..

If number is not a valid octal number, OCT2DEC returns the #NUM! error value.

                          ValueEval numberVE)

Description copied from interface: Function1Arg

see Function.evaluate(ValueEval[], int, int)

Specified by:

evaluate in interface Function1Arg

public ValueEval evaluate(ValueEval[] args,
                          OperationEvaluationContext ec)

Specified by:

evaluate in interface FreeRefFunction

Parameters:

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

ec - primarily used to identify the source cell containing the formula being evaluated. may also be used to dynamically create reference evals.

Returns:

never null. Possibly an instance of ErrorEval in the case of a specified Excel error (Exceptions are never thrown to represent Excel errors).
