loss of signifigant digits

I'm losing signifigant digits assigned to a "double" variable. Is there something I can do to keep them?


For example, when assigning double wavelength with the value of 1527.6051 the program returns wavelength's value as 1527.61.

Do I need to use a different variable type to prevent the rounding?

what are you printing it with?

I'm using cout <<.


cin>> wavelength;
cout<<"You entered wavelength: " << wavelength<<"\n";



is what i'm using.

try this

cin>> wavelength;
cout.precision(6); // set the output precision to 6
cout<<"You entered wavelength: " << wavelength<<"\n";

Thank You!

6 didn't work but 8 did. that's what i was missing.
