Accessing double property

[Cimteker]

Hello,

I am creating a custom log file by reading all numeric values for all tests. The double values as reported by TestStand and viewable in built-in reports look like this:

9.255963134932e+061

Here's CVI code that I use to read them:

    sprintf(keyName,"Locals.ResultList[%d].Numeric",i);
       tsErrChk(TS_PropertyExists(seqContextCVI, &errorInfo,keyName, 0, &propertyExists));
       if(propertyExists){
           tsErrChk(TS_PropertyGetValNumber(seqContextCVI,&errorInfo,keyName,0,&numproperty));
           sprintf(szBuf,"%.5lf",numproperty);

        }

What I get in my report is this:

92559631349317830736831783200707727132248687965119994463780864.00000

Any ideas?

Thanks

Hello Cimteker, 

In line, "sprintf(szBuf, "%.5lf".......",you specifiy szBuf should be written with 5 numbers of precision, which is why your report displays 5 zeros. To log the values in scientific notation, you should change the formatting of sprintf to "%e".

Thanks Haley.

Actually "%.5g" is even a better choice. If you use "%.5e" than 0 is reported as 0.0000E+00. G makes it all nice.

Thanks for help
