I am trying to do a calculation within a Jasper report (java based open source reporting tool).
I have a BigDecimal variable that I need to divide by Integer variable, below is my code, please let me know what is wrong.
varBigDecimal1.divide(BigDecimal.valueOf(varInteger1.doubleValue()))

Why don't you tell us - whats happening that you think is wrong. Looks OK to me! (BigDecimal is immutable so you need to assign the result to another variable though)

My bad..the syntax was ok, its just that the divisor value at runtime was zero. The error message was saying "unable to parse expression.." that made me think something wrong with the variable assignment. Thanks.

There's nothing intrinsically wrong with it, but the redundant double conversion will slow things down.

varBigDecimal1.divide(BigDecimal.valueOf(varInteger1))

will work just as well.

More computing sins are committed in the name of efficiency (without necessarily achieving it) than for any other single reason...including blind stupidity.




Nothing wrong with the advice (it's probably sound) but yet whenever I see someone take about efficiency I love to use that quote ....
 
It is sorta covered in the JavaRanch Style Guide.
