This template builds an alternative form of common or mixed [[fraction]]s, using a [[Vinculum (symbol)|vinculum]] (horizontal line), for [[Wikipedia:Manual of Style (mathematics)|scientific and mathematical text]]. It takes one, two or three parameters: the optional integer (may be signed), the optional numerator and the required denominator; in this order. Note that the three-parameter version is ambiguous and can be taken to mean A + {{sfrac|B|C}} or A · {{sfrac|B|C}}.

; <code><nowiki>{{sfrac|A|B|C}}</nowiki></code> : {{sfrac|A|B|C}} (integer, numerator and denominator)
; <code><nowiki>{{sfrac|B|C}}</nowiki></code> : {{sfrac|B|C}} (numerator and denominator)
; <code><nowiki>{{sfrac|C}}</nowiki></code> : {{sfrac|C}} (denominator only)
