Language: JAVA
The following code sequence is supposed to compare a float and a double with the same value and output that they are equal. What is wrong with the following code sequence? Why is it not showing the correct answer? Write your code to fix the problem.
float piF = 3.141592653589793f;
double piD = 3.141592653589793;
if(piF == piD)
System.out.println("piF and piD are equal");
else
System.out.println("piF and piD are not equal");
a) What is "Approximation Error" in floating-point representation?
Approximation Error - Since in floating point representation we can not represent all real numbers so there occurs an error.It is difficult to represent some decimal numbers in binary form.
b) Why is it happening?
Floating point Approximation error occur because it uses fixed no. of bits to represent decimal numbers.
It is difficult to represent real numbers with the help of fixed bits of binary numbers. Also some decimal numbers are difficult to represent in binary form.
c) How can we minimize it? We can minimise it by-
1.Changing radix
2.Adding numbers of different magnitude value.
3.overflow
4. underflow
5.Subtracting numbers of same magnitude value.
