rand
Generates a random number. The number is from, and including, 1 up to, and including, the input value.
Example:
{{ 100|rand|format_integer }}
Might output “42”.
The rand filter can also generate a floating point value by given it a floating point number or a string representing a floating point number as input. It will generate a number from, but not including, 0 to, and including, the input value:
{{ "4.0"|rand|format_number }}
Might output “3.1415926536”
