This template rounds down (aka “truncates”) a numeric value to a limited number of decimal places.

; Usage<nowiki>:</nowiki>
* <tt><nowiki>{{</nowiki>{{SAYFAADI}}<nowiki>|</nowiki></tt>''value''<tt><nowiki>}}</nowiki></tt>
* <tt><nowiki>{{</nowiki>{{SAYFAADI}}<nowiki>|</nowiki></tt>''value''<tt><nowiki>|</nowiki></tt>''decimals''<tt><nowiki>}}</nowiki></tt>
* Both parameters can be any valid numeric expression.
* The ''decimals'' parameter defaults to 0 and is rounded to the nearest integer.
* ''decimals'' can be negative to round down to a multiple of a power of ten.
* If ''decimals'' is not between -20 and 20, the ''value'' is returned without rounding.

; Examples<nowiki>:</nowiki>
* <tt><nowiki>{{</nowiki>{{SAYFAADI}}<nowiki>|3.14159|3}}</nowiki></tt> = {{{{SAYFAADI}}|3.14159|3}}
* <tt><nowiki>{{</nowiki>{{SAYFAADI}}<nowiki>|0.123|3}}</nowiki></tt> = {{{{SAYFAADI}}|0.123|3}} (should be 0.123, not 0)
* <tt><nowiki>{{</nowiki>{{SAYFAADI}}<nowiki>|0.00032|3}}</nowiki></tt> = {{{{SAYFAADI}}|0.00032|3}} (should be 0, not "-0")
* <tt><nowiki>{{</nowiki>{{SAYFAADI}}<nowiki>|-0.123|3}}</nowiki></tt> = {{{{SAYFAADI}}|-0.123|3}} (should be -0.123, not 0)
* <tt><nowiki>{{</nowiki>{{SAYFAADI}}<nowiki>|-3.14159|3}}</nowiki></tt> = {{{{SAYFAADI}}|-3.14159|3}}

* <tt><nowiki>{{</nowiki>{{SAYFAADI}}<nowiki>|0.31415|0}}</nowiki></tt> = {{{{SAYFAADI}}|0.31415|0}} (should be 0, not "-0")
* <tt><nowiki>{{</nowiki>{{SAYFAADI}}<nowiki>|0|0}}</nowiki></tt> = {{{{SAYFAADI}}|0|0}} (should be 0, not "-1")
* <tt><nowiki>{{</nowiki>{{SAYFAADI}}<nowiki>|-0.31415|0}}</nowiki></tt> = {{{{SAYFAADI}}|-0.31415|0}}

* <tt><nowiki>{{</nowiki>{{SAYFAADI}}<nowiki>|314159|-3}}</nowiki></tt> = {{{{SAYFAADI}}|314159|-3}}
* <tt><nowiki>{{</nowiki>{{SAYFAADI}}<nowiki>|314.15|-3}}</nowiki></tt> = {{{{SAYFAADI}}|314.15|-3}} (should be 0, not "-0")
* <tt><nowiki>{{</nowiki>{{SAYFAADI}}<nowiki>|-314159|-3}}</nowiki></tt> = {{{{SAYFAADI}}|-314159|-3}}

; Note<nowiki>:</nowiki>
* <tt><nowiki>{{</nowiki>Floor<nowiki>|</nowiki></tt>''value''<tt><nowiki>}}</nowiki></tt> is equivalent to <tt><nowiki>{{</nowiki>{{SAYFAADI}}<nowiki>|</nowiki></tt>''value''<tt><nowiki>}}</nowiki></tt>.
