      org.apache.poi.ss.formula.functions.Rank

All Implemented Interfaces:
  Function, Function2Arg, Function3Arg

    public class Rank

extends java.lang.Object

Returns the rank of a number in a list of numbers. The rank of a number is its size relative to other values in a list. Syntax: RANK(number,ref,order) Number is the number whose rank you want to find. Ref is an array of, or a reference to, a list of numbers. Nonnumeric values in ref are ignored. Order is a number specifying how to rank number. If order is 0 (zero) or omitted, Microsoft Excel ranks number as if ref were a list sorted in descending order. If order is any nonzero value, Microsoft Excel ranks number as if ref were a list sorted in ascending order.

### evaluate

    public ValueEval evaluate(int srcRowIndex,
                              int srcColumnIndex,
                              ValueEval arg0,
                              ValueEval arg1)

  Description copied from interface: `Function2Arg`
  see `Function.evaluate(ValueEval[], int, int)`

### evaluate

    public ValueEval evaluate(int srcRowIndex,
                              int srcColumnIndex,
                              ValueEval arg0,
                              ValueEval arg1,
                              ValueEval arg2)

  Description copied from interface: `Function3Arg`
  see `Function.evaluate(ValueEval[], int, int)`

### evaluate

    public final ValueEval evaluate(ValueEval[] args,
                                    int srcRowIndex,
                                    int srcColumnIndex)

  Specified by:
    `evaluate` in interface `Function`
  Parameters:
    `args` - the evaluated function arguments. Empty values are represented with `BlankEval` or `MissingArgEval`, never `null`.
    `srcRowIndex` - row index of the cell containing the formula under evaluation
    `srcColumnIndex` - column index of the cell containing the formula under evaluation
  Returns:
    The evaluated result, possibly an `ErrorEval`, never `null`. Note - Excel uses the error code #NUM! instead of IEEE NaN, so when numeric functions evaluate to `Double.NaN` be sure to translate the result to `ErrorEval.NUM_ERROR`.
