It is counting system of base 2.As I known ,currently we are using countimg system of base 10 ,is also called the decimal system that uses ten symbols :0,1,...,9 to represent numbers .The counting system of base 2 is also called the binary system that uses only two sumbols 0 and 1 to represent numbers.It is used in computer science and digital technology Converts decimal to binary−odd part 1)Procedure •Step 1:We multiply the odd part by a power of 2(say 2^n ,n>1) •Step 2:get the result in step 1 (only take whole part)and then convert to binary •Step 3:divide the result in step 2 by 2^n ,we get odd part in binary form (essentially this step is to move the comma to the left n times) 2)For example •Ex1:Convert 2.5625 to binary 2_(10) =10_2 −Multiply :.5625 ∗(2^4 )=9 −Convert 9 to binary:9_(10) =1001_2 −Divide:1001_2 /(2^4 )=.1001 ⇒2.5625_(10) =10.1001_2 •Ex2:Convert 2.3333 to binary 2_(10) =10_2 −Multiply:.3333∗(2^(16) )=21843.1488 −Convert 21843 to binary: 21843_(10) =0101010101010011 −divide 0101010101010011/2^(16) =.0101010101010011 ⇒2.3333_(10) =10.0101010101010011_2 •Ex3:convert 2.6973 to binary 2_(10) =10_2 −Multiply :.6973 ∗(2^(15) )=22849.1264 −convert 22849 to binary: 22849_(10) =101100101000001_2 −dovide 101100101000001_2 /2^(15) =.101100101000001_2 ⇒2.6973_(10) =10.101100101000001_2

By ′odd part′do you mean fractional part?(see line#11)

$${By}\:'{odd}\:{part}'{do}\:{you}\:{mean} \\ $$$${fractional}\:{part}?\left({see}\:{line}#\mathrm{11}\right) \\ $$

Ok,is also called decimal part of a number.Ex:12.34567245 then its “odd part”is .34567245

$$\mathrm{Ok},\mathrm{is}\:\mathrm{also}\:\mathrm{called}\:\mathrm{decimal}\:\mathrm{part}\:\mathrm{of}\:\mathrm{a} \\ $$$$\mathrm{number}.\mathrm{Ex}:\mathrm{12}.\mathrm{34567245}\:\mathrm{then}\:\mathrm{its} \\ $$$$``\mathrm{odd}\:\mathrm{part}''\mathrm{is}\:.\mathrm{34567245} \\ $$
