Hello: Very simple question, so it seems. The Origin Pro8 version is giving me a hard time converting text/numeric data into scientific notation. For example, my imported ASCII files are labeled with the appropriate numerical lettering (n=nano, p=pico, f=femto) after the numerical value. However, I cannot get the values to convert to scientific notation for further graphing purposes.
i.e. value = -1.2555n; i want to have this cell read = -1.2555e-9.
The previous version required me to convert the column to, engineering, then convert to numerical, then convert to scientific. This process gave me the correct notation and value for further use.
Any help would be appreciated. I am sure it is something simple, but I have tried multiple ways to get this to work, and it seems it does not like the letter designation along with the number value when converting.
thanks much. cheers! |

I should specify, this only happens when the IMPORTED or typed values are FIRST in ENGINEERING notation (ie. -1.222n). Getting the values to convert to scientific notation is where the problem occurs. However, the opposite seems to convert (Scientific notation-->Engineering), without a problem.
Any help is appreciated. thanks

Hi,
I have tried this in all versions of OriginPro 8 (from SR0 to SR6), and find that only SR5 and SR6 can get the result you want. If you are not using SR5 or SR6, please update to SR6 according to this page, and then have a try again.
