HrXMaximum( ), JrXMaximum( ), SrXMaximum( )

Print this Topic Previous pageReturn to chapter overviewNext page

The above functions are similar to functions HrMaximum( ), JrMaximum( ), and SrMaximum( ) except:

1.If the number of races meeting 'fCondition' is smaller than nRaces, the function will return .NULL.
2.Although the functions accept 5 arguments, the 4th argument of HrXMaximum( ), JrXMaximum( ), SrXMaximum( ) will always be ignored.

 

Syntax

HrXMaximum('eValueExpr',nRaces,'fCondition',eDefaultValue,cIncluding)

JrXMaximum('eValueExpr',nRaces,'fCondition',eDefaultValue,cIncluding)

SrXMaximum('eValueExpr',nRaces,'fCondition',eDefaultValue,cIncluding)

 

Argument

Description

Example

'eValueExpr'

Datum the maximum of which is to be found.
Data type of expression: Any

'HrDvdWin( )'

nRaces

Number of latest races, counting back from the underlying race, to be averaged. The races must be meeting the condition specified by 'fCondition'.
If nRaces is omitted, all races meeting 'fCondition' will be included.
If total number of races meeting 'fCondition' is smaller than nRaces, the function will perform calculations on only the available races. You may use the HrCount( ) function to check how many races have been counted.

6

'fCondition'

If argument 'fCondition' is passed, the races (nRaces) will only be selected from those meeting 'fCondition'. The 'fCondition' argument is composed of a For clause and a While clause.
A For clause causes the function to act on each record that meets the specified logical condition.
A While clause causes the function to stop action once the logical expression evaluates to false.
Both For and While clauses are optional.

'For HrFP( )=1 While

HrDate( )>Date(1999,9,1)'

eDefaultValue

Default value returned when no race satisfying the specified condition can be found. The data type of this value must be identical to that of normal return value.


cIncluding

When applying the function to past records, by default, races in the underlying meeting are not included. You may use this argument to change the scope. See the following page for details: The cIncluding Argument.

'R'

 

Returns

Data type of eValueExpr
