This template is the core template of Template:Formatnum. That template handles the empty string and invalid numbers, and the possible minus sign, so that this template needs to handle valid non-negative numbers only. Also Formatnum applies rounding according to parameter prec, if defined, and increases the absolute value so that this template can truncate after a total of 16 digits, and supplies this template with the log to the base 10, rounded down, of this final number.

Parameters

Parameter name Description Default value

1 non-negative number empty
2 language code value of {{int:Lang}}
sep set to any non-empty value to produce a result without thousands separators empty
prec number of digits after the decimal point to show if empty or undefined: 0
oom log to the base 10, rounded down, of the number. empty
