The template has only one required parameter: a real number. These examples use the name of the redirect, {{nts}}, for brevity.

• prefix: To display some text before the number, use |prefix=some prefix{{nts|123456789.00123|prefix=approx. }} → approx. 123,456,789.00123
• format: For unformatted output, use |format=no{{nts|123456789.00123}} → 123,456,789.00123{{nts|123456789.00123|format=no}} → 123456789.00123
• debug: To display the sort key, use |debug=yes.{{nts|123456789.00123|debug=yes}} → 7008123456789001230♠123,456,789.00123{{nts|-123456789.00123|debug=yes}} → 2991876543210998770♠−123,456,789.00123

Apart from the added thousands separators the numbers are formatted as supplied (scientific notation or not, leading and trailing zeros, and a zero before the decimal point or not). This formatting does not affect the sorted order except for numbers not satisfying the limitations mentioned below.
