Hi,

I have a doubt in C. I calculate a value which has a floating point precision about 15 digits eg. 0.000000000000000045. If I use float or double with control strings %f or %lf, I receive the value as 0. How to proceed with this. Your help is greatly appreciated.

Regards,
Beulah

#include<stdio.h>

void main()
{
float a=0.000000000000015;
printf("%0.15f",a);
}

hope u will find this useful.i did this in visualc++ compiler

If possible, such a number should be presented in scientific notation. Saves counting all those zeroes...
