(or ) evaluates any input and produces a normalized yes or no, based on the content of the input and several configurable options. It is not used in article prose, but in coding complex templates.  ব্যবহার  The template distinguishes five different types of input, supplied on the first unnamed parameter:  Yes: Case-insensitive forms of Yes, y, true, and 1; e.g.   No: Case-insensitive forms of No, n, false, and 0; e.g.   Nothing: When the input is defined but either contains no value or consists of whitespace character only; i.e. {{Yesno|}} or   Negation: When the input is either ¬ or entirely missing; i.e.  or   Anything else: e.g.   By default, the template returns "yes" in the first and last case but returns blank in the other cases.  Two short-hand templates for the most common uses that override the default behavior:   or  – always returns "yes" (or the specified replacement result in ) unless an explicit negative value is given; i.e., it evaluates to "yes" even when the value is empty or missing.   or  – always returns "no" (or the specified replacement result in ) unless an explicit positive value is given; i.e., it evaluates to "no" even when the value is present, as long as it does not contain anything that resolves to "yes".   আউটপুট কাস্টমাইজ করা  Template's default output can be customized with five named parameters, respectively: , , ,  and . If these parameters are specified, the template response is as follows:  Yes: Template returns the contents of , otherwise returns "yes". For example:   results in ""    results in ""  No: Template returns the contents of , otherwise returns blank. For example:   results in ""   results in ""  Nothing: Template returns the contents of , or of  in absence of the former; otherwise, returns blank.   results in ""   results in ""   results in ""  Negation: Template returns the contents of , otherwise returns blank. For example:   results in ""  Anything else: Template returns the contents of , or of  in absence of the former; otherwise, returns "yes".   results in ""   results in ""   results in ""  For the named parameters, use of a blank value is not the same as omitting the parameter. A blank named parameter tells the template that the customized return value is blank. For example:   results in ""   results in ""    যুক্তিসম্মত পার্থক্য   Overview of  logical values and their associated texts Inputparameter 1() In code Logical return value Defaultreturn text Return text when set: Note yes, y, true, 1*   "" "" * Case-insensitive (Y=y)    "" "" "" when  no, n, false, 0*   ""  "" * Case-insensitive (N=n)    ""  "" "" when  1=   ""  "" "" when  ¬   ""  ""    ""  ""    Comparison with related templates Input parameter 1 ()    yes, y, true, 1* "" "" ""  "" "" "" no, n, false, 0* ""  "" ""  ""  "" "" 1= ""  "" "" ¬ ""  "" ""  ""  "" ""   স্থিতিমাপের পূর্ণ তালিকা  Unnamed parameter 1= the input value to be evaluated.

When set, each one overrules their default return value.  {{yesno | | yes  = | no   = | blank= | ¬    = | def  = }}   আরও দেখুন   Module:yesno   – slower than Yesno, but can properly handle ref tags inside the parameters   – variant of Yesno that defaults to "yes" if value is not explicitly negative    – variant of Yesno that defaults to "no" if value is not explicitly positive   টেমপ্লেটপাত্ত
