I get the same as Mark, using RPN i did the following: * wl = Wall length: 636 cm * ot = Offset total: 22 cm + 22 cm = 44 cm * pw = Painting width: 64 cm * np = number of paintings: 6
--- * first nail: ot/2 + pw/2 * next nails: (wl - (ot + pw))/(np-1) --- first: <$macrocall $name="rpn" a=<<rpn 44 2 />> b=<<rpn 64 2 />> operation= "+" decimals="2" precision="p" locale="de-CH"/> cm next: <$wikify name="distance" text='<$macrocall $name="rpn" a=636 b=<<rpn 44 64 +>> operation="-"/>'> <$macrocall $name="rpn" a=<<distance>> b=<<rpn 6 1 ->> operation="/" decimals="2" precision="p" locale="de-CH"/> cm </$wikify> Now your turn Josiah, put the four parameters in input fields and use for every wall. :-D Cheers, Thomas Am Sonntag, 11.
