BCB decimal is gone 相除後小數點不見了

I just did math in BCB and found decimal is gone, all 0, even I used double, float, etc........

then I figure out there is one rule in C program which is

interger divide by interger the result is interger. decimal divide by decimal result decimal.

Unless I used decimal, there will not have decimal exist.

the code is modified to force type transforming which means putting an "(double)" right after "=" on your demand.

ex:

int a = 65536, b = 12028;

double c;

c = (double) b/a;
