how to print 5 precision float in c++
#include <iostream>
#include <cstdio>
using namespace std;
int main()
{
// This code helps you to print a number with desired decimal
double Number=10.3454;
printf("%.3lf",Number);
return 0;

}c++ double higher precision then float
For representing floating point numbers, we use float, double and long double.
What’s the difference ?
double has 2x more precision then float.
float is a 32 bit IEEE 754 single precision Floating Point Number1 bit for the sign, (8 bits for the exponent, and 23* for the value), i.e. float has 7 decimal digits of precision.
double is a 64 bit IEEE 754 double precision Floating Point Number (1 bit for the sign, 11 bits for the exponent, and 52* bits for the value), i.e. double has 15 decimal digits of precision.Copyright © 2021 Codeinu
