Float and Double in C
Float and Double:
On this page we will discuss about float and double in C programming language.
Definitions:
Float
- This is typically used for graphic-based libraries since it makes it easier for compilers to manage your programs’ processing capacity.
- Float has single precision.
- The storage required by Float is 4 bytes.
- Float variables can be given a value with a range of 1.2E-38 to 3.4E+38.
- It features a 32-bit floating point precision, according to IEEE.
- It has a precision of six decimal places.
Double
- In programming languages, this is the most used data type for assigning values with a real or decimal-based number within, such 3.14 for pi.
- It has two times as much precision as a float, or double precision.
- Double type variables can be given a value that falls between the ranges of 2.3E-308 and 1.7E+308.
- Double requires storage of 8 bytes.
- It has a precision of 15 decimal places.
- It features a 64-bit floating point precision, according to IEEE.
Example of Float:
Run
#include<stdio.h>
int main()
{
float a = 22.45;
printf("Value of a = %f\n",a);
return 0;
}
Output:
Value of a = 22.450001
Example of Double:
Run
#include<stdio.h>
int main()
{
double d = 567.89732;
printf("Value of d = %f\n",d);
return 0;
}
Output:
Value of d = 567.897320
Example of Float and Double:
Run
#include<stdio.h>
int main()
{
int a = 20, b = 10, sum;
float c = 22.22, d = 22.22, add;
sum = a+b;
add = c+d;
printf("The sum of a and b is = %d\n", sum);
printf("The sum of c and d is = %d", add);
return 0;
}
Output:
The sum of a and b is : 37 The sum of c and d is : -11046240
