Instruction
To handle float, long, or big integer values in user or event attributes, use Jinja.
The round function is not supported in Jinja 2.8 versions; it is recommended that you use the format function instead.
Example
The Jinja syntax must resemble the following:
${{'%0.2f'| format(sumHST | float) }} --> User attribute
${{'%0.2f'| format(EventAttribute.totalTaxLessAllInclusiveTaxes|float)}} --> Event attribute
