The numeric value of TrueVal if Test is true

and the numeric value of FalseVal if Test is false.

numeric value if Test is true, and returning another numeric value if Test is false.

The code inside the IFF function:

 

inputs: 
Test( truefalsesimple ), 
TrueVal( numericsimple ), 
FalseVal( numericsimple ) ;

if Test then
IFF = TrueVal 
else 
IFF = FalseVal ;
