I wish this help you I'm attempting to insert some integers into a Postgres table with the following somewhat simple code. , Instead of:
code :
params[0] = (char*)&i;
#include <endian.h>
/* ... */
int64_t const i_big_endian = htobe64(i);
params[0] = (char*)&i_big_endian;

seems to work fine Using bytearray:
code :
>>> b'\x4c\x00\x46'
b'L\x00F'
>>> a = bytearray(b'\x4c\x00\x46')
>>> a[1] = 255
>>> a
bytearray(b'L\xffF')
>>> bytes(a)
b'L\xffF'
How to write integer value "60" in 16bit binary, 32bit binary & 64bit binary

it fixes the issue Imagine you're writing the decimal value 60. You can write it using 2 digits, 4 digits or 8 digits:
code :
1. 60
2. 0060
3. 00000060
1. 00111100
2. 00000000 00111100
1. 00111100 - 8bit - still the same.
2. 00111100 00000000 - 16bit, bytes are flipped.

Convert Negative-base binary to Decimal in Haskell: "Instances of .. required"

will be helpful for those in need You have your list pattern-matching syntax backwards. In _ : _ the first argument is the head of the list (one element), and the second is the tail of the list (another list). e.g. x:xs matched with "abc" gives x = 'a' xs = "bc". So xs:x should be x:xs. The reason for GHC asking for an instance of Num [Char], is the comparison x == 0 (and x == 1). In this, it is trying to match the type of x (String == [Char]) with the type of 0 (Num a => a), and to do this, it requires a Num instance for String.
The fix is: negbin_dezi (x:xs) n
