Re: floor()

[shoker_17]

To display the output, I used 'save -text 'filename.txt' monoColor;'.

This really doesnt make any sense to me. I do not know what is wrong because
it seems that my prof was able to get this result correctly in his computer
but not me. If I cant solve this problem, its difficult to proceed coding. 

Please HELP!!

Ohh...I am using Linux Ubuntu as my OS while running Octave.
