How do you reverse numbers?

[Kharybdis]

k... this problem is really bugging me.... ive tried to do it for like 3 hrs and i just cant get it to work.

The problem is to get a real number in the range 0 to 1 that contains 3 decimals. Then you reverse the number and display the sum.

Ex. user enters 0.934 and the program adds 0.439 to 0.934
anyone help?

Snip! We don't just provide answers here.

any shorter way? turing =

I suggest you try looking into realstr(), strreal(), and string manipulation

as Clayton points out, working with characters is easier. Though Mathematically, you could also use powers of 10 and floor() function to get individual digits.

String manipulation... i wish i could just do this :
var num,num1 : real
var ans1,ans2,ans3: string


floor(num)
num(3)= ans1
num(4) = ans2
num(5) = ans3
put floor(num) +ans1+ans2+ans3
num1 := floor(num) +ans1+ans2+ans3 (combine those statements not add....)

lol
lots of wrong there.....but that my was my original idea proved wrong.

Well why are you flooring the number as it gets rid of the number? because its between 0-1 which results as 0

[Kharybdis]

Im flooring num. I WANT it to always be zero.

like floor(num)+"." plus ans1 plus ans2 plus ans3.

[Tony]

Actually you're not too far off.

We could probably assume that floor(num) will always be 0. Or rather "0".

And + does join, not add strings.

or intstr() and strint(). Depends on if you get a hold of digits before or after you convert everything into a string.

i got it like the day after i posted this ....
final answer is..

var num : string
var num1, number : string
put "Please enter a number in the range of 0 to 1. Must contain 3 decimals."
get num
num1 := num (5) + num (4) + num (3)
number := "0." + num1

put "The sum of your number, and its reverse is ", strreal (number) + strreal (num)

lol took me 3 hrs to figure out a 3 minute typed code.

Its not error trapped or proofed or anything like that. If you enter 0.2341 or 0.12 it crashes. or even 1.242

Heh, it actually should be this way. If you figure something out in 3 minutes, but it takes your 3 hours to type it up -- you're doing something very very wrong (and I did see this happen).

[Kharybdis]

Its not necessarily that case. What if you were given a project to do with a concept idea, but even though the idea is very simple, it takes a lot of time to actually make it work. Still, i basically agree with ya.
