[br]Hello,

i have a problem with Origin C. I programmed a function to convert hexadecimal values in decimal values.
The programm works very good in my code builder. But if i want it to use in the Origin worksheet I get values like 2.32504E8 ??
I think the problem is the parameter passing from the column where the hexadecimal values are located.
How can i programm it?

Here is the code:
[code]
#include <stdio.h>
#include <math.h>
#include <string.h>

int hex(String hexzahl)
{
	int dec_sum=0, i=0, length=0, dec;
	
	length = strlen(hexzahl);	
	length--;
	
	for ( ; length >= 0 ; length--)
	{
    	switch(hexzahl[length])
		{
			case '0': dec=0; break;
			case '1': dec=1; break;
			case '2': dec=2; break;
			case '3': dec=3; break;
			case '4': dec=4; break;
			case '5': dec=5; break;
			case '6': dec=6; break;
			case '7': dec=7; break;
			case '8': dec=8; break;
			case '9': dec=9; break;
			case 'A': dec=10; break;
			case 'B': dec=11; break;
			case 'C': dec=12; break;
			case 'D': dec=13; break;
			case 'E': dec=14; break;
			case 'F': dec=15; break;
			default:  break;
		}
		
		dec_sum+=dec*(16^i);
		i++;
 	}
 	
 	
//	printf("\nDecimal: %d", dec_sum);
	return dec_sum;

} [/code]

I hope anyone can help me.

Thank you very much.

Kind regards
Patrick

patrick031284	Posted - 09/19/2007 : 05:46:24 AM Thank you for your help. But it didn't still work. I change the values in my column into strings (text). Do I have to write your example-code in my script or do i have to change anything in my script? Kind regards Patrick
Mike Buess	Posted - 09/17/2007 : 11:24:50 AM Hi Patrick, Your function works fine if you pass the cell values as strings as in this LabTalk script... for(i=1;i<9;i++) { %A=cell(i,1)$; // row i, col 1 as string cell(i,2)=hex(%A); }; Note: LabTalk has a built-in hex function... quote: hex(string) The hex(string) function returns the base 10 equivalent to the hexadecimal value represented by the given string. The maximum number of hex characters in the given string is 4. Mike Buess Origin WebRing Member
