Train yourself to use == when making comparisons (some languages use 3 equals signs socount your blessings). Be careful to avoid mixed-type comparisons - if you compare a floating point number with an integer the equalitytests may not work as expected.You can use else in combination with if - e.g.if(num

If atleast one <strong>of</strong> the numbers is a real, the result will be a real. This explains why later in this document you'll sometimes see 2.0 beingused instead <strong>of</strong> 2 - I want to force real division to be done.[show extra information] (index.php?reply=extraArithmetic#Arithmetic)While Loops [ back to contents (#Contents) ]For repetitive tasks, use loops. Easiest is the while loop - code that repeatedly runs while some condition is true. Here's an exampleint num=1;while (num
