I am trying to convert IPv4 addresses from integer to string for display. I found this example code but don’t know how to convert the python right shift and bitwise to Clarion code. The Clarion BSHIFT and BOR /BXOR take longs and I’m not sure the integer fits in the long.
def int_to_ipv4(ip_int):
“”“Converts an integer to an IPv4 address string.”“”
octets =
for i in range(3, -1, -1):
octet = (ip_int >> (i * 8)) & 0xFF
octets.append(str(octet))
return “.”.join(octets)
Example usage
ip_int = 3232235617 # Example integer representing 192.168.1.10
ipv4_address = int_to_ipv4(ip_int)
print(f"Integer: {ip_int}, IPv4 Address: {ipv4_address}")
Explanation:
i * 8: Right shifts the integer by 24, 16, 8, and 0 bits to isolate the octets.
& 0xFF: Performs a bitwise AND with 0xFF (which is 255 in decimal or 11111111 in binary) to mask out all bits except the least significant 8 bits (the octet).
