How can I represent double type number in binary form, for example:
dec = 3.14159
to an array consists of its IEEE 754 Double precision binary representation as binaryconvert.com does it
bin = 0100000000001001001000011111100111110000000110111000011001101110
in Matlab? I know there is a similar question, but not for Matlab.
You can do the following:
hexdec = num2hex(dec);
bin = hexToBinaryVector(hexdec);
Example:
hexToBinaryVector(num2hex(pi))
ans =
1100000000001001001000011111101101010100010001000010110100011000
hexToBinaryVector is in the Data Acquisition toolbox. I have most toolboxes with my academic install, but I don't think this one is common unfortunately. Also, the first bit (the sign bit?) seems to be opposite of what is returned by @LuisMendo's answer and the URL in the OP's question.This can be done with typecast(...,'uint8') to get invididual bytes; then fliplr to change byte endianness (at least that's needed on my machine); then converting each byte to binary with dec2base(...,2,8); and finally reshape'ing to a single row:
bin = reshape(dec2base(fliplr(typecast(dec,'uint8')),2,8).',1,[]);
