Problems with division

[Cristian Eriksson]

Hallo forum!: First post

Until now I ´ve solved all problems on my own, by googeling. But this as puzzled me for months.

 

I´ve either figuerd ways around it or ignored it. It´s only in some functions it shows up...

   if(AboveCounter>BelowCounter&&AboveCounter>0&& BelowCounter>0) xBias=NormalizeDouble(AboveCounter/BelowCounter,2);
      if(BelowCounter>AboveCounter&&AboveCounter>0&& BelowCounter>0) xBias=NormalizeDouble(BelowCounter/AboveCounter,2);

      Alert("Depth ",xRangeDepth," ",AboveCounter," ",BelowCounter," ",xBias);

Why is xBias only getting round numbers, like 1.0, 2.0, 3.0 when the variables AboveCounter and Belowcounters  can be 18/32, 45/19, 15/27 etc..

If anyone could help me I would be very thankfull!

I solved it!!

For some mysterious reason, you can´t divide two ints and get a double.. Hmm, I don´t see the logic in that.

Try reading this article on typecasting.

The relevant bits are these examples:

Examples:

int    i=1/2;        // no types casting, the result is 0    Print("i = 1/2  ",i);      int k=1/2.0;         // the expression is cast to the double type,    Print("k = 1/2  ",k);  // then is to the target type of int, the result is 0      double d=1.0/2.0;    // no types casting, the result is 0.5    Print("d = 1/2.0; ",d);      double e=1/2.0;      // the expression is cast to the double type,    Print("e = 1/2.0; ",e);// that is the same as the target type, the result is 0.5      double x=1/2;        // the expression of the int type is cast to the double target typr,    Print("x = 1/2; ",x);  // the result is 0.0
