The following example shows how you can perform a conditional 
assignment inside a Formula Node.

Consider a code fragment that computes the square root of 

x

 if 

x

 is positive, 

and assigns the result to 

y

. If 

x

 is negative, the code assigns –99 to 

y

.

if (x >= 0) then

y = sqrt(x)

else

y = -99

end if

You can implement the code fragment using a Formula Node, as shown in 
the following illustration.
