[Scilab-users] Whay False

[Rafael Guerra]

Hi Paul,

Note that reel-0.05 = -1.804D-16  not zero.
You need to use error bars to test equality of reals, ex:  if abs(reel-0.05)< %eps  (or <N*%eps)

Regards,
Rafael

Hi All,

I spent a lot of time in looking for an issue in my code ; finally I found the origin but I do not understand why ... probably a very basic reason :|

Any suggestion regarding the code here after ?

Thanks

Paul

a = 2.05

entier = int(a)
reel = modulo(a,2)

if ( reel == 0.05) then
    chaine = '05'
elseif (reel == 0.5) then
    chaine = '50'
else
   chaine = '00'
end

printf("chaine = %s\n',chaine)

// Nota
reel == 0.05 // whay False ?????
