Provides support for doing simple mathematical operations in templates.

PARAMETERS

1) calculate - Required. Alows you to input a string consisting of numbers,
symbols of mathematical operations and round brackets, e.g
calculate = “(10 + 5) / 3”. Symbols of supported mathematical operations are:
+ (addition), - (subtraction), * (multiplication), / (division),
% (division remainder), ++ (increment),—(decrement).

2) invalid_input - Optional. Accepts two values: “alert” and “silence”.
Default value is “silence”. If the value is “alert”, then in cases when
the plugin has some problem with parameters,  PHP alert is being shown;
if the value is “silence”, then in cases when the plugin has
some problem with parameters, it finishes its work without any alert being shown.
Set this parameter to “alert” for development, and to “silence” - for deployment.

3) var1, var2, var3, var4 ... var48, var49, var50 - Optional. Allows you to input numbers.
Used to gain more security - the values of these parameters will be checked if they really are numbers.
Each these parameters can be used inside “calculate” parameter. E.g. var1=“10” var2=“5” var3=“3” calculate=”({var1} + {var2}) / {var3}”

4) on_non_numeric_vars - Optional. Allows you to specify what variable {math_plus_result} should output in case
some of var1, var2, var3, etc. variables were found to be non numeric.

USAGE

Use this plugin as folllows:

{exp:simple_math calculate="(10 + 5) / 3"}

Or use it this way:

{exp:simple_math calculate="({var1} + {var2}) / {var3}" var1="10" var2="5" var3="3"}
