How to get binary representation of a decimal number

Hi, all

I am looking for a method that can convert a decimal number to binary vector. I know there are many answers that I can google it, but seems there's nothing fits my problem.

I need to convert a decimal number (can be both positive or negative, and has a long string after decimal point) into binary. And at some point, I have to convert the binary strings back to decimal numbers.

I've found a function ?dec2bin?, but seems it just convert the integer part, for instance, the result of dec2bin(1.87) is 1.

May I know if there's any functions that can help me?

Thank you very much.

Best regards
Wenlong
