Does anyone know why 0.0 divide by 0.0 give something that is not a number?



It return something like "-nan(ind)"
Any idea how to fix it?

because the result of dividing zero by zero is not possible. even the calculator on windows will say not defined, python and java and c++ will give a null and or divide by error error or crash. You can tell a program to return a zero if there is a zero division and you can catch it before it happens using a lexer /parser or exception. Even simple math how many time will zero go into zero? you might think 1 but no u cant put nothing in nothing. if oyu want to fix it if divided <>0 then print (a/b) else print "divide by zero error"

In EVERY good programming language, it gives you a compile or runtime time error that division by zero is not possible.

@Chmava: Do an IF check on your divisor if you don't know the value upfront.

Division by zero has been undefined behaviour in mathematics since the invention of zero in the 6th century, its a fundamental baseline rule, division by zero is forbidden!
