Hello, Everyone.

What does the -float- --- mean .PNG

The question : What does the " float ---> -1.0097419586828951109e-28 " mean ?

and What does the " float ---> - 5.0487097934144755546e-29 " mean ?

Need help with brief explanation.

Thanks in advance for the time and help.

The float keyword does not just affect the precision of the displayed values, it also affects the precision used in the calculations. So when you use the float keyword the symbolic processor is also subject to the effects of numerical roundoff. Try "float,250" to increase the precision from the default of 20.

Thanks in advance for the time and help.
