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!! -Richard Adams radams AT mail DOT diac DOT com
