テンプレート:Formatnum/1/docのソースを表示

{{Documentation subpage}}
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.
