Шаблон:Numkey
Use
This template creates an invisible sort key prefix based upon a real number for use in sortable tables with mixed numbers and text or merely text. This template creates a valid sort key with an accuracy of one part in 10,000,000,000 for real numbers in the ranges 1e-300 to 1e300 and -1e-300 to -1e300. If the absolute value of the real number is greater than 1e300, this template creates a key representing infinity. If the absolute value of the real number is less than 1e-300, this template creates a key representing infinitesimal. If the input variable is not a real number, this template does not create a key.
The syntax for this template is:
{{numkey|var1}}
where:
- var1 = any real number
- NOTE: var1 may not contain thousands separators
