function qwordToByteTable(Number) : table
Converts a QWORD (8 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 QWORD (8 bytes) only the lower portion of the number will be used.
i.e.: 0xFFFFFFFFFFFFFFFF00 : 0xFFFFFFFFFFFFFF00
8 7 6 5 4 3 2 1 0 7 6 5 4 3 2 1 0
Function Parameters[edit]
| Parameter | Type | Description |
|---|---|---|
| Number | number | The number to convert to a byte table |
Examples[edit]
local bt = qwordToByteTable(0xFFFFFFFFFFFFFFFF)
--7 6 5 4 3 2 1 0
writeBytes('00123ABC', bt)
Code:
local bt = qwordToByteTable(10)
for i, v in ipairs(bt) do
print(i - 1, string.format('%02X', v))
end
Output:
0 0A 1 00 2 00 3 00 4 00 5 00 6 00 7 00
Code:
local bt = qwordToByteTable(10.9)
for i, v in ipairs(bt) do
print(i - 1, string.format('%02X', v))
end
Output:
0 0A 1 00 2 00 3 00 4 00 5 00 6 00 7 00
Code:
local bt = qwordToByteTable(0xFFFFFFFFFFFFFFFFFF00)
--8 7 6 5 4 4 3 2 1 0
for i, v in ipairs(bt) do
print(i - 1, string.format('%02X', v))
end
Output:
0 00 1 FF 2 FF 3 FF 4 FF 5 FF 6 FF 7 FF
