When i try this:

PHP код:

new a = 500;
new b = 10;
new c = floatround( b/100*a );
printf("Result: %d", c); 


I get 'c' = 0, but the correct answer is 50. Wtf? Why?

pawn Код:

floatround(c, floatround_ceil);

PHP код:

new a = 498;
new b = 7;
new Float:d = b/100*a; // it's 34,86
new c = floatround( d ); // it's 35
printf("Result: %d", c); 


What's wrong?

The right part gets executed first and then the result is written to the part on the left. Define your operands as a float with the appropriate tag, or use float(), or use any of the float functions (floatmul, floatdiv). It might also simply work like this, although I'm not entirely sure;

pawn Код:

new Float:d = b/100.0*a;

The '.0' is important. Actually that should be done at all times when working with floating point values in Pawn. Even in functions like SetPlayerHealth, etc.

But really in pawn not observed mathematical action order?
Anyway thanks, i try this 'b/100.0*a' and it works.

I didnt't ignore your post, i just didn't consider it helpful, because given expression IS a float, but you wrote that it isn't..

new Float:a = 500.0; 
new Float:b = 10.0; 
new Float:d=b/100*a
new c = floatround(d,  floatround_ceil); 
printf("Result: %d", c);

******, i respect you and your jobs, but really, this answer wasn't enough informative for me. "Neither of your inputs are floats", and what? Why they arent'a floats? What should i do with this? Your knowledge is your knowledge and i can't read your mind, so i asked this topic question

Rittik, thank you, i already understood
