## Class Oct2Dec

- java.lang.Object
- - org.apache.poi.ss.formula.functions.Fixed1ArgFunction
  - - 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.

          public Oct2Dec()

  - ### Method Detail

    - #### evaluate

          public ValueEval evaluate(int srcRowIndex,
                                    int srcColumnIndex,
                                    ValueEval numberVE)

      Description copied from interface: `Function1Arg`
      see `Function.evaluate(ValueEval[], int, int)`
      Specified by:
        `evaluate` in interface `Function1Arg`

    - #### evaluate

          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).
