How can I change from real # to binary #?

Question

I want to change from real number to binary number to use python coding.
but it is very hard to me... help me

Answer 1

result = str(bin(remainder)) + str(bin(decimal))
?

Answer 2

It is a built in function in Python. There are
hex(4) returns hex value of 4
bin(7) returns binary value of 7
oct(5) returns oct value of 5
Here is an example:

Answer 3

oh, it's nice. but it is not what I want.
example, i put 3.3, then output is '101.010101....' and -4.4 is '-100.110011....'

Answer 4

This is my coding but it is not complete.
decimal = int(input('num:',))
result = ''
while (decimal > 0) :
remainder = decimal % 2
decimal = decimal // 2
result = str(remainder) + result
print((result))
