Test-If

Hi Folks

Could we please install the ParserFunctions MediaWiki extension ? See - http://meta.wikimedia.org/wiki/ParserFunctions

Many thanks ATB Paul

Ignore the rest of this page as it won't work without ParserFunctions

Some results from parser function parameters:

If Tests

If tests look to be working ok.

ifeq

{{#ifeq:{{lc:AbC}}|abc|yes}}  should evaluate to 'yes' 

Result = yes

{{#ifeq:banana|abc|true|false}}  should evaluate to 'false' 

Result = false

{{#ifeq:yellow|yellow|true|false}}  should evaluate to 'true' 

Result = true

ifexpr

{{#ifexpr: 10 > 9 | yes | no}}  should evaluate to 'yes' 

Result = yes.

{{#ifexpr: 9 > 10 | yes | no}}  should evaluate to 'no' 

Result = no.

Other
( )	Grouping operators	{{ #expr: (30 + 7) * 7  }}	259
mod	"Modulo" truncates the numbers to whole numbers, divides the left number by the right, and returns the remainder that could not be divided. Note: div and mod are different from all programming languages.	{{ #expr: 30 mod 7 }} {{ #expr: -8 mod -3 }} {{ #expr: 8 mod 2.7 }}	2 -2 0
round	Rounds off the number on the left to the power of 1/10 given on the right.	{{ #expr: 30 / 7 round 4 }} {{ #expr: 30 / 7 round 1 }} {{ #expr: 1911 round -2 }} {{ #expr: -2.5 round 0 }}	4.2857 4.3 1900 -3

To Investigate

May require other template(s). Though AFAIK I don't need these.  ;-)

{{#len:string}} for string = 123456789 should evaluate to '9' 

Result = {{#len:123456789}}

{{#pos:string|target|offset}}  should evaluate to '10' 

Result = {{#pos:blah blah target in string|target|offset}}

Table Row Test

I'll need to remove my workaround attempts.
