Post subject:  base 10 to base 2
This is the program I made in class that converts base 10 number to base 2
try it lol

8) 8)
code:
var count : int := 0
var base_10 : int
var temp : int
put "Enter a number that's base 10."
get base_10
temp := base_10

loop
    count := count + 1
    base_10 := base_10 div 2
    exit when base_10 = 0
end loop
var base_2 : array 1 .. count of int
for ii : 1 .. count
    base_2 (ii) := temp mod 2
    temp := temp div 2
end for
put "The base 2 number is "..
for decreasing x : count .. 1
    put base_2 (x) ..
end for

Would you like to know about the easier way to do that?

you mean:

code:
var base_10 : int
get base_10
put intstr (base_10, 0, 2)

Just decimal to binary... has no real use really. Unless you like doing calculations in binary.

rofles... binary has tones of use... if u do alot of contest problems, you'll see alot of problems involving filling bins or disks... and binary is quite useful plus its the fundamentals behind computers.. how can any geek not love binary?

I agree
binary is very useful when doing programming or wanna know how a computer work
but not common in evryday life 8)

code:
var la:string
var base : int
get la
base:=strint (la,2)
put base

thats change from base 2 to base 10 I think .... Shocked Rolling Eyes

ok u want teh actual formula?
tsktsk
didnt listen in class did u?
Laughing
ok now
base 2 to base 8

code:

100101011
group them first by 3
[100][101][011]
then see 0*1 + 0* 2+ 0*4= 4 the first group is 4
same thing, the second one is 5, the thrid one is 3
thus, the number is 453

for base 2 to base 16
same thing as above, except group by 4

for base 10 to 2 look at the code above
for base 10 to 8

divide by 8 and get the reminder reverse it
thats it
