Hi i've got a problem with units. After the calculation of a function Smath Studio shows a result like this : B(3.25*'m)=0.6246*'m^{{16386721669152500000000000000000-1638672166915250*10^16}/{5000000000000000*10^16}} The exponent of the meter unit is almost zero ; so => m^0 = 1 => there should be no unit. When i calculate the result directly (without first defining the function) i get : ({b+h}/L(3.25*'m))^0.63 = 0.6246 This result is right. (no unit) When i change the function parametes (f.i. 0.63 => 1.5), the strange unit vanishes. I think it's got something to do with dividing by a very small number somewhere internally. I don't know how to post the sm file or a picture. Can someone help me ? Edited by user 15 October 2010 00:20:08(UTC)

Dear housen, It would certainly be easier to answer your question if we could see it within Smath. Please see this wiki page for help on posting images and Smath expressions: Notes on Using the Forum |

Thanks for the fast reply. After reading the starters page, here's a screenshot : As you see : 1st result : 0.62*'m^{{16386721669152500000000000000000-1638672166915250*10^16}/{5000000000000000*10^16}} (which actually is similar to 0.62 m^0 = 0.62) 2nd result : 0.62 which is correct.

Hello housen,
If the result looks like this as it was by calling function B(z), then there is likely to be connected with the symbolic processor of SMath.
Just select the definition of function B(z), then right click and choose Optimization|Numeric, or choose from the menu Calculation|Optimization|Numeric. After that you will have by calling the B(z)=>
B(3,25m)=0.62
