Logic operators

The calculations in AlisQI do support basic logic operators (and + or).
You can create simple if then else statements with the ? and : operators.

In fact, the calculation engine has many advanced features. Read the documentation on the advanced calculation engine to learn about all of its capabilities.

If you want to combine conditions with a logical AND use "and" or "&&" (ampersand).

conditionA and conditionB

If you want to combine conditions with a logical OR use "or" or "||" (pipes).

conditionA or conditionB

If (condition) then (A) else (B)

Can be defined as:

condition ? A : B

Imagine a form to calculate the surface of an area (either a square or a circle).
We have the fields: {length}, {width} and {radius}.

Now you want the calculation to be smart enough to distinguish the area type, based on the inputted dimensions.

If the radius is specified, use:

{radius}*pi^2

Otherwise, use:

{length}*{width}

This can be combined in a single evaluation:

{radius} ?  {radius}*pi^2 : {length}*{width}

If you want to use the value of the condition in the then leg of your evaluation, simply use the ?: notation.

condition ? condition : B

can be condensed to

condition ?: B

Combine conditions with logical AND / OR operators.

AND operator

if ConditionA and ConditionB then 1 else 0 can be defined as:

ConditionA and ConditionB ? 1 : 0

OR operator

if ConditionA or ConditionB then 1 else 0 can be defined as:

ConditionA and ConditionB ? 1 : 0

Be aware that operators are case sensitive.
