Hello,



*** UPDATE***

I made some homework and changed the question, to be straight forward.

I run the below code in both Zorro and Microsoft Visual Studio C:

Code
function main(){
	double a1 = 0.56434;
	double a2 = 0.56506;
	printf("\n %.10e", (a1-a2)/a2);
	
	double a3 = 0.58299;
        double a4 = 0.56434;
        printf("\n %.10e", (a3-a4)/a4);
}


On Zorro I got:

Zorro 2.66.3
(c) oP group Germany 2025


returns compiling........... ok

-1.2742435919e-003
3.3047445653e-002



On VC and a calculator, I got:

-1.2742009698e-03
3.3047453663e-02


It seems that Zorro used float calculation, it's not clear to me why?


Thanks
David
