how string binary ieee 754 representation of 32 bit float? example 1.00 -> '00111111100000000000000000000000' you can struct package: import struct def binary(num): return ''.join(bin(ord(c)).replace('0b', '').rjust(8, '0') c in struct.pack('!f', num)) that packs network byte-ordered float, , converts each of resulting bytes 8-bit binary representation , concatenates them out: >>> binary(1) '00111111100000000000000000000000' edit : there request expand explanation. i'll expand using intermediate variables comment each step. def binary(num): # struct can provide float packed bytes. '!' ensures # it's in network byte order (big-endian) , 'f' says should # packed float. alternatively, double-precision, use 'd'. packed = struct.pack('!f', num) print 'packed: %s' % repr(packed) # each character in returned string, we...
