char representation of a double

[senorbuckwheat]

Hi,

I am looking for a way to convert a double to the char representation, ie. put double, which is eight bytes, to char[8];
Example:

double nDb = 12.34;
char szDb[8];

szdB would hold the character representation of nDb which might look something like:
[0] 0''
[1] 0''
[2] 0''
[3] 0''
[4] 0''
[5] 0''
[6] 51'3'
[7] 64'@'

Well, if you mean that you want to access the bytes that make up the representation of the double you can simply do:

char *sDb = (char *)(& nDb);

However the representation is not exactly trivial, if you want more info on that I wrote quite extensively in the following thread:
