easy one keep the no dividing by 2 until remainder comes to 0 and 1 and then write the quotient of each division in reverse order i.e. starting from bottom..
U can use the DOUBLE-DABBLE method to convert binary to decimal. Just go on dividing the number by unless u reduce the full no. Consider simple no. like 14.625 I think u r facing problems with the digits after decimal. like 0.625 Multiply the no by 2--------------0.625x2= 1.25---------------------1 Now multiply 0.25 by 2 so, 0.25x2=0.5-------------------------0 Now multiply 0.5 by 2 so, 0.5x2=1-----------------------------1 Do this only till three decimal places. therefore binary of 14.625 is 1110.101
