i'm in need of converting a decimal number(double datatype) to a binary number. The inbuilt matlab function dec2bin supports only 16bit conversion with no decimal point precision. can't i convert a number greater than 65536(2^16) using matlab?? also pls help me in converting a floating point decimal number to binary...
thanks in advance...

Dear Goutham,

Please specify what "binary" number means.

Which version are you using?

>> dec2bin(99999)
ans =
11000011010011111
>> dec2bin(2^52+1)
ans =
10000000000000000000000000000000000000000000000000001


If you want to convert a floating point number to binary, you can start
with num2hex() which will convert a single precision or double precision
number to the hex representation of IEEE 754

>> num2hex(pi)
ans =
400921fb54442d18


In the past I have posted floating point to binary conversion routines
(and vice versus)
