IfNotSimple

ifnotsimple(value, value if not simple)

IfNotSimple is a convenience function that only includes text if a given value is not already simplified. It only has an effect when used with the Uns(implified) display style.

The most common usage would be to display a fractional result of a probability question. For example, you might have a probability question where the result might be 45/100. In this case, you might want to display the 45/100 AND the simplification 9/20. If the answer was 43/100, you do not need to simplify anything.

{ifnotsimple($f/$n," which simplifies to {simplify($f/$n)}")}

This command will result in

45/100 which simplifies to 9/20

or

43/100

depending on the values of $f and $n

If the overall display size is set to Uns
