Major New Parameters Command

The latest versions of FX Draw and FX Equation have added an IF command. This represents a major increase in the power of the parameters system and allows authors to create significantly more powerful MultiDocs.

An example If command might look like this…

{if($d=0,”Cannot divide by zero”,$n/$d)}

If you included this command in a question, the inline calculator will look:

  • Look at the value of the $d parameter
  • If $d is zero, the command will add the words “Cannot divide by zero” to your equation.
  • If $d is not zero, the command will divide the value of the $n parameter by $d and output the answer.

In addition to the new IF command, we have added a number of other Boolean commands that make it easy to write conditions for IF commands. These include:

  • And
  • Or
  • Xor
  • Nor
  • Not
  • IsEven
  • IsOdd
  • IsInteger
  • IsComposite
  • IsPrime
  • IsFactor
  • IsNatural
  • IsCube
  • IsSquare

The new IF command is available for use now but we anticipate that its power will allow us to add a variety of new features. Keep an eye out!
