Hello,

I have a following problem. When I'm trying to convert radians to degrees or vice versa I have a result -- (two dashes). What's wrong?


Origin Ver. 8 and Service Release 0
Operating System: Win7 x64

Hi wojtek,

I suspect that your data in the cells in the worksheet column have been stored as text strings rather than the numeric values. In a typical situation, the former appear left-adjusted, and later appear right-adjusted in the cells.
You can double-click the column header of your data to show the Column Properties dialog, and change the column's "Format" to "Numeric" rather than the default "Text & Numeric" to force them to be converted to the numbers.

I hope my suspect is your actual situation. If it isn't, please describe where is your data, and in which way you have tried to convert your data.

Hi Hideo,

Thanks for reply. Unfortunately it is not a reason. I've tried this but I got error even when I make the same calculation in Command Window. I attached example on picture below.



I have also access to newer version of Origin and the problem doesn't exist but now I have to use this version. Any other suggestions?

Hi wojtek,

The built-in functions, degrees(x) and radians(x) seem to have been introduced in Origin 8.5.1 . You can define them (e.g, in the script window beforehand) by yourself as:
degrees(x)=180*x/pi;
radians(x)=pi*x/180;

Thank you Hideo! I resolved this problem before in same way as you proposed. I was just wondered what's wrong. I thought that if I try to use function which is not defined I get error text in the Command Window.
