Hi. I have a question. I'm new to C. I'm writing an application that
needs the extra precison of double-length floating point numbers
rather than the single-precision float type. I'd like to be able to
print out the double-floating-point variables, but how? I have tried
the following but it doesn't work:

#include <stdio.h>
#include <math.h>

void main(void)
{
	double a=3.125978724;
	
	
	printf("The variable a is:\n\t");
	fprintf ("%f\n", &a);
	
	return;
}

I get an "incompatible pointer type" warning. How can I print out the
value of a double-precision floating point variable? Any help at all
will be greatly appreciated...:)  Thank you!!
