Int2Hex

wrapper for dec2hex, to handle 64bit + signed numbers via typecast

Description

[sorry - uploaded wrong version, this one runs...]

Matlab's dec2hex (which converts 'integers' to hex, donno why 'dec' in mentioned), rejects all unsigned types, and 'int64'.
And that's the perpuse of this wrapper.
ofcourse, dec2hex - could just be fixed.

• MATLAB release: MATLAB 7.4 (R2007a)

why not simply

dec2hex(double(int64_var))

Response to comment:

dec2hex(double(int64_var)) doesn't work because it loses precision. You won't get all of the bits of the int64 or uint64 represented in the result.

Could you please give an example of the syntax to call this function?

For example, how could I convert the decimal/floating point numbers:

15
-15
1056546.1498564
-975465154.168784

Into a hexadecimal format. This would be very helpful to me in 64bits, but would really prefer 72bits right now. Is there anyway to generate a 72bit result for a hexadecimal number that would then be 18 characters long?

sorry, I meant to write decimal/fixed point numbers not floating point
