Calculating Percentages

[kav123]

I am trying to calculate the percentage value. The values for which the percentage needs to be calculated, they are coming from a database, they are coming fine.
This is what i am doing:

percent = (cCount/totalCount)*100;

Although i am getting values for cCount and totalCount, the total percentage always comes zero.
The 'percent' variable is of float type.

Looks like a simple thing, but am i missing something really basic here.
The values i am getting i.e. cCount and totalCount are both float.

my guess is 100 is an integer by default. (cCount/totalCount) is implicitly converted to an int before multiplying my 100 which would be 0. 0*100=0.
try this instead

float cCount = 2;
float totalCount = 10;
float one_hundred = 100;
float percent = (cCount/totalCount)*one_hundred;

or

percent = (cCount/totalCount)*100F;

the F after 100 allows the system to interpert the 100 as a float rather than the default (int) type. If the flag is not F it's something like that
M = decimal
D = double
etc.

Jason, the flag is definitely F.

Both the variables cCount and totalCount need to be of type float.

If he only needs integer part, he can simply use
percent = 100*cCount/totalCount;
and he will get whole part

Meh sorry, I thought both cCount and totalCount were integers.
