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? |

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 |

Im flooring num. I WANT it to always be zero. like floor(num)+"." plus ans1 plus ans2 plus ans3. |

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. Clayton @ Thu Oct 11, 2007 8:53 pm wrote: I suggest you try looking into realstr(), strreal()
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). |

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. |
