BigDecimal Division

[vk01]

Hi,

 

Does this division work only for the integers? I need to use "division" for two BigDecimal values.

 

Thanks!

When using BigDecimals you need to use the mathematical operators defined in the BigDecimal class. So if you need to divide two BigDecimals create an expression of type BigDecimal and use "bigDecimalOne.divide(bigDecimalTwo, BigDecimal.ROUND_HALF_UP)", which gives you the result of a your variable bigDecimalOne divided by the variable BigDecimalTwo.

You can get the value of a BigDecimal as an integer by calling intValue() on it, and then create an Integer from that.

 

Be careful though - if iReport thinks the returned value is a BigDecimal, that probably means that the field is declared in the database to be large enough to overflow an integer.
