calculating percentages

[dspain]

i know calculating percentages is simple common math we all learned in the 4th grade but im having a problem, porting it to code (man its been over 25yrs)

ok problem 1 is calculating a percentage of numbers less than 100,
this will always be a 1 correct?

INT dmg = 13;

dmg+= (dmg *.05); /* adding the 5% bonus to the damage */

dmg would equal 1 always right? cause that would equal 13.65?

INT dmg = 362;

dmg+= (dmg * .05); /* adding the 5% bonus */

now we get 380.1 so (int)dmg would = 380? and (double)dmg would be 380.1?

the second problem is giving me a bit more trouble, i want to do something similiar to the above problem but pull the percent based off stat value.

im dividing strength by 5 and using that as a percent.

so:

INT strength = 20;
INT bonus = (strength/5);

/* bonus is 5% */

INT dmg = 15;
dmg+=(dmg * .bonus); /* i know this isnt right just to give ya an idea */

how would i add the value bonus as a percent to damage?

appreciate any help i could get on this.

dmg would equal 1 always right?

Actually, damage would equal 13 here. dmg + dmg * 0.05, 13 + 13*0.05, 13+13/20, 13/20=0 in integer math.

And to get a percentage, like x%, you just divide x by 100.0
