Question

Is it somehow possible to only display the fraction digits with fmt:formatNumber? I basically need to render a price-like double in two fields: decimal and fraction digits (123.456 -> 123 456) and I want to avoid string splitting etc. 🙂

The solution has also to work with a minimum number of fraction digits in order to create for instance this:

123.1 -> 123 01

The data represented is a price that is stored as a decimal number for some reason.

minFractionDigits="2" would produce .01 as output for the second field.

Another output example would be:

123<span>01</span>

Answer 1

Yes:

<fmt:formatNumber maxIntegerDigits="0" />

Update:

How about multiplying by 100, 1000 or something like that, and outputting it as integer digits. Say:

<fmt:formatNumber maxIntegerDigits="3"  value="${yourValue * 1000}" 
     maxFractionDigits="0" />

Thus you will have to trim some decimal digits, though.
