Union float return

Float_Read(ptr)

/*Value to be stored to EEPROM */
char xdata *ptr;
{


union
/* UNION to access the bytes of int */
{
float i;
char split[4];
}data_trans;



data_trans.split[0] = Read_EEPROM(ptr);

data_trans.split[1] = Read_EEPROM(ptr+1);

data_trans.split[2] = Read_EEPROM(ptr+2);

data_trans.split[3] = Read_EEPROM(ptr+3);

printf("Float in Function=%\n",data_trans.i);

return (data_trans.i);


}

when the function return the float then its zero but the value of float in same function is right,
Is it any problem with return statment?
