This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I'm printing currency values to the screen using <fmt:formatNumber>. If my numeric value has a non-zero fractional part I want exactly two decimal places. If the fractional part is zero I want the decimal places omitted.
so 45.75 prints as $45.75
but 201.00 prints as $201
So that means that 18.30 should print as $18.30 and not as $18.3? In that case I think you're going to need two different formatters and some kind if-then-else to distinguish the two cases. Writing a custom tag might be the right way to go here.
Ah. I thought that no-trailing was an undesirable outcome.
In that case, I'd simply use the ternary operator to choose between the two patterns.

Is there anything in the fn library that can perform decision in a robust way? All I can think of is to check if the String representation of the value ends with ".00", and that sounds ugly. BTW does Oracle have a documentation page for EL? Thank you.
