function dwordToByteTable(Number) : table
Converts a DWORD (4 bytes) to a byte table, interpreting it as an integer.
Note: If the number is a float only the integer no greater than or no less than the given value will be used.
Same as value from 'math.floor'.
i.e.: 8.1 : 8, 8.9 : 8, -8.1 : -8, -8.9 : -8
Note: If the number is larger than a DWORD (4 bytes) only the lower portion of the number will be used.
i.e.: 0xFFFFFFFF00 : 0xFFFFFF00
4 3 2 1 0 3 2 1 0
Function Parameters[edit]
| Parameter | Type | Description |
|---|---|---|
| Number | number | The number to convert to a byte table |
Examples[edit]
local bt = dwordToByteTable(0xFFFFFFFF)
--3 2 1 0
writeBytes('00123ABC', bt)
Code:
local bt = dwordToByteTable(10)
for i, v in ipairs(bt) do
print(i, string.format('%02X', v))
end
Output:
0 0A 1 00 2 00 3 00
Code:
local bt = dwordToByteTable(10.9)
for i, v in ipairs(bt) do
print(i, string.format('%02X', v))
end
Output:
0 0A 1 00 2 00 3 00
Code:
local bt = dwordToByteTable(0xFFFFFFFF00)
--4 3 2 1 0
for i, v in ipairs(bt) do
print(i, string.format('%02X', v))
end
Output:
0 00 1 FF 2 FF 3 FF
