Problem statement

Input a float value and we have to print the input value by specifying/setting different decimal precision in C.

Example

Input:
Enter float value: 12.34567

Output:
12
12.3
12.35
12.3457

Setting decimal precision

To set decimal precision, we use the following format specifier with the printf() statement,

%.0f : No digit after decimal point
%.2f : 2 digits after decimal point
%.4f : 4 digits after decimal point

Program

# include <stdio.h>

int main ()
{
	float value;	

	printf("Enter float value: ");
	scanf("%f", &value);

	//print without decimal point 
	printf("%0.0f\n", value);
	//print 1 digits after decimal point
	printf("%0.1f\n", value) ;
	//print 2 digits after decimal point 
	printf("%0.2f\n", value) ;
	//print 4 digits after decimal point 
	printf("%0.4f\n", value);

	return 0;
}

Output

Enter float value: 1.234567
1
1.2
1.23
1.2346
