Dividing numbers that will result a float ? - Ahmad45123 - 08.01.2015

I know this may be a noob question... But...

pawn Код:

printf("%f", 2 / 10);

It prints 0.00000... Why ?

pawn Код:

printf("%d", 2 / 10);

I think this doesn't need to be a float.

It will result 0 too.
As 2 / 10 will result in a fraction.

Код:

printf("%.2f", 2.0 / 10.0);

Let the compiler know that you want float result, by setting at least one constant to float:

pawn Код:

printf("%.2f", 2.0 / 10);

(the precision format (.2 part) is not required for this to work)

my bad
printf("%.2f", 2.0 / 10.0);

2 and 10 must be floates also
