I'm confused. Why isn't this using the new syntax?
Don't know! Seems to be a problem with the answer display only in this particular mode for complex numbers in the answer ({a4+b4_i})/({a5+b5_i}).
In the main body (prompt and statement) all is displayed correctly.

Switch the collectNumbers (7th switch) off and one and reveal answer in both cases. Clearly a problem when switched off. Also as 16th bit is switched on was expecting fraction display.
