How can I rounddown or roundup the rezults ?

for i=1 to 10

print sqr(i)

next



'I want the result to be rounddown or roundup (depend how the result are :<=x.5 or >x.51)

Try this...
for i=1 to 10
   print sqr(i), using( "#.###", sqr( i))
next


PS note that code displays better ( as here) if you click the [C] button and paste in the indicated space.

Sorry .5 rounds up like .51 using Print using, 5's are commonly rounded up.
for i=.4 to .6 step .01
   print i, using( "#", i)
next

How can I rounddown or roundup the rezults

as you see, int(x) in JB rounds towards zero
here are user-defined functions
ceil() - always round up
floor() - always round down

I want the result to be rounddown or roundup (depend how the result are :<=x.5 or >x.51)

As Bplus noted, this is unusual requirements.
Usually .5 and above rounds up, anything less then .5 down.
using() works like this.
int(x+.5) on positive x works like this.
Of cource it could be done - scroll below - but very likely you shouldn't really do that.

Then we debugged that calculator program what did beam loads (balances) we had function like
round(number, decimalPlaces), but I was not able to find that thread.

Custom round function example - <.51 down, >=.51 up

for i=.4 to .6 step .01
   print i, using( "#", i), customRound(i)
next

function floor(x)
   floor = int(x)
   floor = floor - (x <> floor and x < 0)
end function

function ceil(x)
   ceil = int(x)
   ceil = ceil + (x <> ceil and x > 0)
end function

function customRound(x)
'I want the result to be rounddown or roundup (depend how the result are :<=x.5 or >x.51)
   frac = x mod 1   'tested on positive x
   if frac <.51 then
        customRound=floor(x)
   else
        customRound=ceil(x)
   end if
end function
