Hi,
I have used erfc() in my kerneland I am using SW_Simulation.
for (int i = 0 ; i < n_elements ; i += BUFFER_SIZE)
{printf("%f\n", erfc(0.35));}
the program runs but the result is just like the bellow lines. the first 0.0 output and a lot of Nan out put. What should I do? could you please help me?
0.000000

Hi, @ramin_rasoulinezhad ,
Have you tried SDx 2018.2? I don't see the issue in 2018.2 with erfc and erf.

Another try:
for (int k=+100;k>-100;k--){
ali = erfc(k * 0.01);
printf("&&%g\n", ali);
}
output:
&&-5.48613e+303
&&-5.48612e+303
&&-5.48612e+303
&&-5.48612e+303
&&-5.48612e+303
.... (just like the last one)

I am using 2017.2. Is it OK?
In this version, all the mathematic functions work except erf and erfc. Which version do you recommend? I am downloading 2018.2 now
Regards,
Ramin
