Hi,
I'm using the fitting function organizer (of origin 8.1)and i have a problem when i try to compile in the origin code builder.

This is my code:

#pragma warning(error : 15618)
#include <origin.h>
// 
void _nlsfcfitqhi(
// Fit Parameter(s):
double V0, double popF2q1, double popF2q2, double popF1q1, double popF1q2,
// Independent Variable(s):
double x,
// Dependent Variable(s):
double& y)
{
	// Beginning of editable part
	
	y=(V0*(popF2q2*(exp(-(((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/6,7)^2))*cos(-1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))+exp(-(((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/(2*6,7))^2))*cos((-1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/2+3*(-0,00662*x^2)/4+(-0,00018*x^3))+exp(-(((-0,00662*x^2)/6,7)^2))*cos(-0,00662*x^2)+exp(-(((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/(2*6,7))^2))*cos((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/2+3*(-0,00662*x^2)/4-(-0,00018*x^3))+exp(-(((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/6,7)^2))*cos(1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31)))+popF1q2*(exp(-(((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/(2*6,7))^2))*cos((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/2-3*(-0,00662*x^2)/4-(-0,00018*x^3))+exp(-(((-0,00662*x^2)/6,7)^2))*cos(-0,00662*x^2)+exp(-(((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/(2*6,7))^2))*cos((-1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/2-3*(-0,00662*x^2)/4+(-0,00018*x^3)))))
	 /(V0*(popF2q1*(exp(-(((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/6,7)^2))*cos(-1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))+exp(-(((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/(2*6,7))^2))*cos((-1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/2+3*(-0,00662*x^2)/4+(-0,00018*x^3))+exp(-(((-0,00662*x^2)/6,7)^2))*cos(-0,00662*x^2)+exp(-(((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/(2*6,7))^2))*cos((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/2+3*(-0,00662*x^2)/4-(-0,00018*x^3))+exp(-(((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/6,7)^2))*cos(1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31)))+popF1q1*(exp(-(((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/(2*6,7))^2))*cos((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/2-3*(-0,00662*x^2)/4-(-0,00018*x^3))+exp(-(((-0,00662*x^2)/6,7)^2))*cos(-0,00662*x^2)+exp(-(((1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/(2*6,7))^2))*cos((-1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))/2-3*(-0,00662*x^2)/4+(-0,00018*x^3)))))

Please, don't tell me my fitting function is too long

The error that appears is:

i was a little bit surprised when i saw that "exp" and "abs" are considered as unknwon functions because i used these into another fitting function without problem.

I need help, pleeeeeeeeeeeeeease

Bye.

While Origin is generally pretty good at handling number systems that use ',' as the decimal point, certain ambiguities can arise in C (and Origin C) when parsing such numbers - particularly when they occur within functions where the parser is looking for ',' as argument separators.

The messages about not finding functions abs and exp are somewhat erroneous in that what Origin really could not find was a prototype for those functions that have multiple arguments - due to the use of ','.

You need to modify your function by putting protective parentheses around all such ambiguous numbers.

Here is one snippet from your function and how it had to be fixed:

cos(-1,43*abs(0,35*x-0,022)-0,43*abs(x-0,31))
needs to be changed to:
cos((-1,43)*abs((0,35)*x-(0,022))-(0,43)*abs(x-(0,31)))
