How to customize number format in freemarker?
freemarker, html, java, number-formatting
Solution
You can also try `?string(",##0.00")`. However in this case you need to explicitly add `$` and `-` sign would be after `$` in case of negative numbers.
<#local total = 3343434/>
$ ${total?string(",##0.00")} //$ 3,343,434.00
<#local total = -3343434/>
$ ${total?string(",##0.00")} //$ -3,343,434.00
OR in case if you want what was expected you can replace the strings.
<#local total = -3343434/>
<#local total = "$ " + total?string(",##0.00")/>
${total?replace('$ -','- $')} //- $3,343,434.00
Problem
I am using freemarker and trying to display numbers in this format: `$3,343,434.00` for example. This was easily taken care of by using `${total?string.currency}` (assuming "total" is some number). However, when I have negative numbers, it's showing them like this: `($343.34)` instead of this: `-$343.34`. I need the negative sign instead of the parenthesis. Is there a way I could customize the formatting so it does everything that the `string.currency` did but replace the negative value behavior? I am relatively new to freemarker, so detailed responses are appreciated!
