Hi to all.
Working in C with PIC24FJ128GA006.
3 buttons that work with LCD men=F9

I want too let the user put in a number, with range -500,0000 to +500,0000

i am trying this code:

void LongBannerChangeField(char increment){
volatile int delayCount;
float LNdata;
if(_uLongBannerSetup){
   ReadLONG();
   LNdata =3D _long.data;

   if (_uLongBannerCurPos =3D=3D LN_BNR_POS_CENTINAIA){
      if(increment) LNdata =3D (LNdata + 100.00);
      LONGSetIntervallo(LNdata);
   }//LN_BNR_POS_CENTINAIA
     =

   if (_uLongBannerCurPos =3D=3D LN_BNR_POS_DECINE){
      if(increment) LNdata =3D (LNdata + 10.00);
      LONGSetIntervallo(LNdata);
   }//LN_BNR_POS_DECINE

   if (_uLongBannerCurPos =3D=3D LN_BNR_POS_UNITA){
      if(increment) LNdata =3D (LNdata + 1.00);
      LONGSetIntervallo(LNdata);
   }//LN_BNR_POS_UNITA
     =

   if (_uLongBannerCurPos =3D=3D LN_BNR_POS_1000){
      if(increment) LNdata =3D (LNdata + 0.1);
      LONGSetIntervallo(LNdata);
   }//LN_BNR_POS_1000

   if (_uLongBannerCurPos =3D=3D LN_BNR_POS_0100){
      if(increment) LNdata =3D (LNdata + 0.01);
      LONGSetIntervallo(LNdata);
   }//LN_BNR_POS_0100

   if (_uLongBannerCurPos =3D=3D LN_BNR_POS_0010){
      if(increment) LNdata =3D (LNdata + 0.001);
      LONGSetIntervallo(LNdata);
   }//LN_BNR_POS_0010

   if (_uLongBannerCurPos =3D=3D LN_BNR_POS_0001){
      if(increment) LNdata =3D (LNdata + 0.0001);
      LONGSetIntervallo(LNdata);
   }//LN_BNR_POS_0001
      WriteLONG();
   }//_uLongBannerSetup;
}//LongBannerChangeField

I would like that when a digit gets to 9 it returns to zero without =

incrementing the digit just above. ?!?
Any help?

LONGSetIntervallo(LNdata); just looks if we are out of range

Thanks
Stefano
