Hello Every one, I cant seem to understand the past threads about this problem so i created mine. So here it is. Im trying to show step by step solution on some certain problem i.e D = A + B + C where A= 0.2 in B= 0.1 in c= 0.5 in So in order for smath to show the formula, you need to go to D := A + B + C ------> RIGHT CLICK OPTIMIZATION--->NONE D = 127m/25000 + 127m/50000 + 127m/10000 ------> RIGHT CLICK OPTIMIZATION--->NONE D = 0.203 m ------> RIGHT CLICK OPTIMIZATION--->NUMERIC the question i would like to ask is, Why does my input value automatically converts to FRACTIONS and in meter when the optimization is converted into none attached here is the file.  problem in unit analysis of optimization none.sm (6kb) downloaded 8 time(s).

Actually that None Optimization is not a feature to show your variable values. SMath stores every number as a fraction acceptable. Units as basic SI units. So when you entered 0.256 it is stored as 256/1000, 32/125 eventually. If you entered 1.2* 'in, it shall be stored as 381/12500* 'm. 1* 'mm shall be depicted as 0.001* 'm in SMath. Optimization None is just a workaround for that purpose. Not a students notebook style to state variables openly as they please. A simple trick you can say, nothing more. Regards PS: You can eval() variables individually but they will be stored with SI units. You can define your own variable just for that printing purpose. But they will be incompatible with other units.

A simple trick you can say, nothing more. Thanks for the information. is there a plugin for smath to store decimals as decimals instead of fractions? or set the main units to english?

thanks man i really appreciate your reply You can hide anything between area boundaries. Insert > Area from menu is how you do it. This is the easiest way I could think of. If you set the option from File>Page Setup, those areas won't show in plot. Regards
