Floating error

Postby stefanols » 31 May 2017

Hi,

Hope that someone can help.

I have problem with floating error. I know that it is because you are deviding with zero.
I have tried though to multiply with 1.0000001 but it does not help.

Anyone that can suggest a better way to write the code below?

Thanks in advance.

Best regards
Stefan
Value1= ((C+2*StdDev(C,20)-average(C,20)) / (4*(StdDev(C,20)))*100);

Something like this:
value1=(C+2*StdDev(C,length)-average(C,length))*1.0000001;
Value2=(4*(StdDev(C,length)))*1.0000001;
Value3= ((value1)/(value2)*1.000001) *100;

stefanols,

what if Value2 = -0.000001?

I would suggest to check if the denominator of a division is different than 0 (for every division that you perform within a code). If it is, do the division otherwise you can do something else (optional).

For example:

Code: Select all

if denominator <> 0 then
result = numerator / denominator
else
result = 0 ;
