Function of multiple outputs produces only one answer or three with a redundant 'ans' . How to fix?

I only want the two output outlined in the function with the corresponding titles
but this produces only one answer 'ans':
function [ampres,amplevels] = ADconverterAmps(bits,rangeVolts)
ampres = (rangeVolts)/(2^(bits));
amplevels = [2^(bits)];
end
While this produces three including a redundant value for ans which is the first output anyway
function [ampres,amplevels] = ADconverterAmps(bits,rangeVolts)
ampres = (rangeVolts)/(2^(bits))
amplevels = [2^(bits)]
end

Use a semicolon (;) at the end of each line to suppress the output to your Command Window:
function [ampres,amplevels] = ADconverterAmps(bits,rangeVolts)
ampres = (rangeVolts)/(2^(bits));
amplevels = [2^(bits)];
end
When you call the functions, put a semicolon at the end of the function call line to suppress the function output displaying to the Command Window:
[ampres,amplevels] = ADconverterAmps(bits,rangeVolts);
That should work.
See the documentation on Special Characters [ ] ( ) {} = ' . ... , ; : % ! @ (link) for details on it and others.

Ah I didn't realise you have to specify the output variables when writing the command to store in the workspace.
So yes, no semi-colons within the function script but then a semi-colon following the command did the job
