Why guess? That's what the standard library functions are for:

#include <math.h>
#include <stdio.h>
int main()
{
   double mantissa, number;
   int exponent;
   number = 3.1415;
   mantissa = frexp(number, &exponent);
   printf("The number %f is ", number);
   printf("%f times two to the ", mantissa);
   printf("power of %d\n", exponent);
   return 0;
}

Output (16-bit DOS program, TC++ 3.0 used):
The number 3.141500 is 0.785375 times two to the power of 2
