function wordToByteTable(Number) : table
Converts a WORD (2 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 WORD (2 bytes) only the lower portion of the number will be used.
i.e.: 0xFFFF00 : 0xFF00
2 1 0 1 0
Function Parameters[edit]
| Parameter | Type | Description |
|---|---|---|
| Number | number | The number to convert to a byte table |
Examples[edit]
Code:
local bt = wordToByteTable(0xFFFF)
--1 0
writeBytes('00123ABC', bt)
Code:
local bt = wordToByteTable(10)
for i, v in ipairs(bt) do
print(i - 1, string.format('%02X', v))
end
Output:
0 0A 1 00
Code:
local bt = wordToByteTable(10.9)
for i, v in ipairs(bt) do
print(i - 1, string.format('%02X', v))
end
Output:
0 0A 1 00
Code:
local bt = wordToByteTable(0xFFFF00)
--2 1 0
for i, v in ipairs(bt) do
print(i - 1, string.format('%02X', v))
end
Output:
0 00 1 FF
