Float Precision in C
In C, float data type represents single-precision floating-point numbers. It typically occupies 4 bytes (32 bits) in memory and provides around 7 decimal digits of precision.
Example:
#include <stdio.h>
int main() {
float a = 0.111111111111111;
float b = 0.222222222222222;
float sum = a + b;
printf("Float: %.20f\n", sum);
return 0;
}
Output
Float: 0.33333334326744079590
Float Precision or Single Precision in Programming
Float Precision, also known as Single Precision refers to the way in which floating-point numbers, or floats, are represented and the degree of accuracy they maintain. Floating-point representation is a method used to store real numbers within the limits of finite memory in computers, maintaining a balance between range and precision.
