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

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
