Negative # reverse

[con.focus]

im trying to get this code to work with megative number

code:

function reverseNumber (rev : real) : real     var snum : string     var srevnum2 : string := ""     snum := realstr (rev,0)     for decreasing i : length (snum) .. 1         srevnum2 += snum (i)     end for     end for     result strreal (srevnum2) end reverseNumber    var rnum : real put "Enter an number" get rnum put "The reverse of your number is: ", reverseNumber (rnum)

i keep getting this error string passed to 'strreal' is not in correct format do i need to add another for deacresing statement if so wut

Well, if you want the negative sign (-) to be before the reversed number, try this:

code:

function reverseNumber (rev : real) : real     var snum : string     var srevnum2 : string := ""     snum := realstr (abs (rev), 0)     if sign (rev) = -1 then     %you could just use if rev < 0 but this is more fun ;)         srevnum2 += "-"     end if     for decreasing i : length (snum) .. 1         srevnum2 += snum (i)     end for     result strreal (srevnum2) end reverseNumber var rnum : real put "Enter an number" get rnum put "The reverse of your number is: ", reverseNumber (rnum)

Otherwise, if you want it at the end (as if everything were reversed), you're going to need to output a string. For that, try this:

code:

function reverseNumber (rev : real) : string     var snum : string     var srevnum2 : string := ""     snum := realstr (rev, 0)     for decreasing i : length (snum) .. 1         srevnum2 += snum (i)     end for     result srevnum2 end reverseNumber var rnum : real put "Enter an number" get rnum put "The reverse of your number is: ", reverseNumber (rnum)

EDIT: notice my post is a little hard to read? It's because everything has been shoved to the right due to your over-sized avatar. Please, shrink it down.
EDIT EDIT: much better
