X=156.102".  Are you asking how to convert decimal numbers into binary form?  Are you asking how many bits would be required to do that?  The answer to such questions would all depend on the format and accuracy in which the numbers are to be represented as well as their magnitude.  Please explain your request in much, much greater detail.  Show us some specific examples of what you wish to do.> > Roger Staffordhello, Roger I mean that the integer of x=156 and I need only 8 bit to represent the no. in good accuracy and x=0.102 the fractional could be represent good accuracy in 7 bit only . and then I don't need more than (8+7=15) 15 bit to represent x .I wish it will be clear
