I need to write a function called truncate that takes a floating-point value as its input and truncates (discards) the value after a specified decimal point before returning the modified floating-point value. It should be possible to call your function from the command window using the following: >> res = truncate(5.672, 2); % results in res = 5.67 >> res = truncate(5.677, 2); % results in res = 5.67 >> res = truncate(-5.672, 2); % results in res = -5.67 >> res = truncate(-5.677, 2); % results in res = -5.67
thanks!

Yes, it can be "fixed" to accomplish that.
