Why java math Is not mathing?

Question

If I divide a number in java by zero, it outputs an error. Makes sense! Example (5/0)
But if I divide an double by zero, it output "infinite". Why? Example (5.0/0)

Answer 1

Java handles integer and floating point division by zero differently:

Integer division by zero (5/0) throws ArithmeticException because integers have no way to represent infinity

Floating point division by zero (5.0/0) returns Infinity because the IEEE 754 floating point standard (which Java follows) has special values to represent positive/negative infinity

This happens because 5.0 is a double, and floating point types have built in representations for infinity, while integers do not.
