modulus - integer division ?

[Aurel]

when i try to implement modulus division in my interpreter i see that something is
wrong modulo operator ,is that true or i don't know something 
this code exit with 9 

Code: [Select]

'modulus - integer division ?
float a,b
int m
a=7:b=2
m=a % b
print str(m)
.

[Aurel]

hmm i found that i must use function
mod(a,b)   ...right?
BUT when i try this i get wrong result
mod(7,2) should be 3 not 1  ?

Code: [Select]

'modulus - integer division ?
float a,b
float m
a=7:b=2
m=mod(a,b)
print str(m)
.

Code: OxygenBasic

1. print 7/2      'result 3.5 (float division)
2. print 7\2      'result 3 (integer division)
3. print mod(7,2) 'result 1 (remainder of integer division)
4.

wait ....
so i must use backslash ....i never know 
ok ..thanks Charles 

[Aurel]

well
directly in o2 result is ok - 3
but when i add it to interpreter then i get weird result ...
oh man...

yes something is wrong ...
it is ok if second operand is number or variable but problem begin
when is second operator function()
like in my case:

'modulus -> integer division
    If Look = "%"   
      Gosub getchar
      iValue = Value \ Factor()
      print "Modulo:" + str(iValue)
      Value = iValue   
    End If

sorry Charles but i think that you must fix this...
thanks...

What is factor?

[Aurel]

factor is a function which return a value ..nothing special
i will give you example :

[Aurel]

try this :

Code: [Select]

'modulus - integer division ?
float a,b
float m
a=7:b=2
m=a\b
print str(m) + " Ok"

function factor(float f) as float
float ff
ff=f+1
return ff
end function

m= a \ factor(1) 'use func factor()
print str(m) + " weird?"

I get a result of 3 and 3, which is correct

[Aurel]

ahh i mean integer division not the rest of division...
Charles...
i found that my wrong result is because i use older oxygen .dll 479kB
so i use new 472kB ...i am not sure is this latest version but now work
properly and give me result 3...

[Aurel]

noooo
With new version of oxygen dll i have problem with strings in fact if i increase window
title text then interpreter don't want execute code ...geez 
where i can find latest oxygen dll?

[Aurel]

ok i found latest (i hope) from here :
http://www.oxygenbasic.org/forum/index.php?topic=1298.0
and it looks that work properly
