Set the template number format

This article describes how to control the formatting of numbers when they are printed from Freemarker.

Define the default number format for use in a template

The number format setting can be used to define a default format to use when a number is printed from a Freemarker template. This can be set in your .ftl file or an imported macro library.

For example: Set number to print with commas for the thousands separators, and a full stop for the decimal point. A variable containing the number 1234567.89 will be printed as follows:

<#setting number_format="#,###,###.0">
<#assign examplenumber=1234567.89 />
The example number is ${examplenumber?string}

will print

The example number is 1,234,567.89

Define the number format when a variable is printed

The number format used by a Freemarker template You can control this using the ?string builtin for numbers.

For example: The following will ensure that the kmFromOrigin value will format the number with commas, and always display at x.x at a minimum (ie. zeros won’t be suppressed for 0.1 or 21.0)

${s.result.kmFromOrigin?string("###,###,##0.0")}
