need some advise with a program for a game
ok, so i need help mostly with making the decimals round to 2 places (ie.0.50)
i'm not the best at this, so if you wnt to change mroe of it, to make it easier to use / understand i'd be extremely thankful :)
heres the code:
//Undead Armory
//Made by
//Mulch
//property of Undead Nation / TEA.
// This is a program that will calculate the cost of the undeads armor, then
//Calculates the WA/WB/DA/Price of all of it...

Why the heck would you need this many variables...??
as i said, not very good.. and i this is stil a rough draft.. jsut making sure everythings going to work fine.
Round a float or double to a precision of 0.01:
Round a float or a double to a precision of 0.05:
If cou continue like this your game (even if it stays a small game) will need about 100k of lines of code ;)
You could let it automatically choose instead of if(type == 5)..., if(type == 6)... etc.
(int)((floatValue + 0.005) * 100) / 100.0Round a float or a double to a precision of 0.05:
(int)((floatValue + 0.025) * 20) / 20.0If cou continue like this your game (even if it stays a small game) will need about 100k of lines of code ;)
You could let it automatically choose instead of if(type == 5)..., if(type == 6)... etc.
oh yea.. jsut to mention.. this isnt a game.. it's FOR a game.. fkor the game Lordsoflegend. im jsut making this.
and where would i put that line/lines? :( i wish i was better at this.. lmao

Ok, personally if you only ever need two decimal places then I'd store the numbers *100 and use integer arithmetic, then output
cout << ( num/100) << '.' << setw(2) << setfill('0') << (num%100)
because you can't exactly represent all numbers 0.01-0.99 in floating point format. You end up with roundoff errors.
cout << ( num/100) << '.' << setw(2) << setfill('0') << (num%100)
because you can't exactly represent all numbers 0.01-0.99 in floating point format. You end up with roundoff errors.
On a slightly different area than asked for, maybe you should put all them if's into a switch statement?
A switch wouldn't make much of a difference. Some kind of a lookup table or anything like this would be much more appropriate so you wouldn't have to write 8 orde more times the same thing.
