Description

A report function that calculates the quotient of two summed fields (columns) from the data source. This function produces a global total. The total sum of the group is known when the group processing starts and the report is not performing a prepare-run. The sum is calculated in the prepare run and recalled in the printing run.

The function can be used in two ways:

to calculate a quotient for the entire report
to calculate a quotient within a particular group

This function expects its input values to be java.lang.Number instances.

The function understands three parameters.

dividend parameter is required and denotes the name of an Item Section field which is used as dividend.
divisor parameter is required and denotes the name of an Item Section field which is used as divisor.
group parameter denotes the name of a group. When this group is started, the counter gets reset to null.
