HOW TO USE MATH MACRO WITH FIELDS:
As with the calculator tiddler, the macro can be used with variables for
input from other sources.
<ragscalculator $(num1variable)$ $(operatorvariable)$ $(num2variable)$>>
macro with values 32, 64 typed in:
<<ragscalculator2 32 add 64>>
= 96
values 32, 64 read from fields:
<$set name="n1var" value={{!!filter-field1}}>
<$set name="n2var" value={{!!filter-field2}}>
<<ragscalculator2 $(n1var)$ add $(n2var)$>>
</$set></$set>
96
macro in a list generating a table, reading values from fields:
<table>
<tr><th></th><th>field 1</th><th>field 2</th><th>macro output</th></tr>
<$list filter="[prefix[zz test pg]]">
<$set name="n1var" value={{!!filter-field1}}>
<$set name="n2var" value={{!!filter-field2}}>
<tr><td>{{!!title}}</td><td>{{!!filter-field1}}</td><td><$view
field="filter-field2"/></td>
<td><<ragscalculator2 $(n1var)$ add
$(n2var)$>></td></tr></$set></$set></$list></table>
field 1field 2macro output
zz test pg1 12 24 36
zz test pg2 27 18 45
zz test pg3 72 18 90
zz test pg4
11 11
zz test pg5 -5 -25 -30
zz test pg6 12 -12 0
To expand this for exponents, ie: 4 to the 4th power, a macro
<<tothepower basenumber multiply powernumber>>
could take "basenumber" (four) for both numbers in a multiply filter, save
the result to a field/variable to insert into another multiply filter using
the variable for both numbers of the filter, repeating "powernumber" number
of steps.
