How to read a char array like a double value?

[ernytony]

Hi,
this is my problem:
I have a char array (it contains 4 bytes rappresenting a double) , how can I read this array like a double value?

Thanks in advance folks

P.S. I'm working on a PIC 16F877.

Hi ernytony,

I am not sure, but you can use "(double)" fornt of array, char variable convert to double. For example ;

char array[4];
(double)array[0];

so char array[0] is converted to double. Good luck

dear asahin11,

the all 4 bytes array of char is the rappresentation of the unique value of my double number, to say that every char is a byte of my 4 bytes rappresentation value in double, so I need to convert all the array like a unique double value.

Thanks

Re: Char Array to double

char tab[4]; // -- it's your table

double doubleVal = *(double *)tab; // assingn value from your tab to variable doubleVal

this is what You want?

will work 100% if size of double is 4 bytes
