I was making a calculation of E.pot = m*h*g, m= 65kg h=3,5m g=9,82m/s^2
if I write 'h*m*g=' I get 2234,05J, but if I write
'E.pot:=m*g*h E.pot=' I get 2405,9J

Hello,

I think you've made some mistake here.
Please attach the problematic SMath file to the post.

Regards,
Radovan

Hi jenspraest,

It's not a bug, just a behavior...


Please hold the mouse on the [MATH lang=eng]E.pot[/MATH] definition... you can see that SMath assign all available variables, so when you make a call to [MATH lang=eng]E.pot[/MATH] only the [MATH]h[/MATH] value will be replaced; to have the "right" behavior you need to place the definition before the variable assignments or to create a function [MATH lang=eng]E.pot(m,h)[/MATH]

regards,

This is already a known behavior - see this post:

overridung variables depends on position of variable assignment
