I'm making a simple calculator for this homework, and Java is returning "Infinity" when divided by 0.
I need to display some error message, when I get infinity. The problem is I don't know how to do the condition
double result; result = 4/0; //if result == infinity then some message - need help with this

The Double class in Java supports infinity. You can implement positive infinity or negative infinity.
The isInfinite() method of Java Float class returns a Boolean value for the specified float object or for 'v'. This method returns true if the argument passed is infinitely large in magnitude and returns false for finite floating-point arguments.
The IEEE Standard for Floating-Point Arithmetic (IEEE 754) defines the NaN value. In Java, the floating-point types float and double implement this standard. Java defines NaN constants of both float and double types as Float.
You can use Double.isInfinite(double)

The above code produces
ArithmeticException: / by zero You can catch this exception in a try/catch block.
