[SOLVED]Very Very Very Strange ??? - Calculate bug? - Jeffry - 03.01.2011

Hello guys,

I wanted to calculate some jackpot things, like 9/10, but pawno didn't do this:

Test:

pawn Код:

printf("%0.2f", 9/10);
printf("%0.2f", 9/100);
printf("%0.3f", 9/1000);
printf("%0.4f", 9/10000);
printf("%0.9f", 9/100);
printf("%f", 9/1000);
printf("----------");
printf("%0.2f", 5/3);
printf("%0.9f", 9*0.01);  //Same as: 9/100, just with multiplicate

And I get:

pawn Код:

[17:20:51] 0.00
[17:20:51] 0.00
[17:20:51] 0.000
[17:20:51] 0.0000
[17:20:51] 0.000000000
[17:20:51] 0.000000
[17:20:51] ----------
[17:20:51] 0.00
[17:20:51] 0.089999996

=> Well, the last one is nearly correct, but the others fail.

Have I done something wrong, or is this a pawno bug?
I'd be happy about help, or people who could test this themself, if they have the same problem.

Perhaps this would be because you're dividing an integer and not a float. You should try:

pawn Код:

printf("%0.2f", 9.0/10);

Or better, use the Floatdiv function.

printf("%0.3f",floatdiv(9,1000));

Ah, Thanks alot guys. Both works, but the result is like the 'printf("%0.9f", 9*0.01);' (0.089999996), but floatround will do it. ^^
Thanks again, and have a nice evening.
