function wordToByteTable(Number)

Converts a word (2 bytes) to a byte table.

Function Parameters

Parameter	Type	Description
Number	number	The number to convert to a byte table

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 porsion of the number will be used.

i.e.: 0xFFFF00 : 0xFF00

Examples

Code:

 local bt = wordToByteTable(0xFFFF)
 writeBytes('00123ABC', bt)

Code:

 local bt = wordToByteTable(8)
 for i, v in ipairs(bt) do
   print(i, string.format('%02X', v))
 end

Output:

 1 08 
 2 00 

Code:

 local bt = wordToByteTable(8.9)
 for i, v in ipairs(bt) do
   print(i, string.format('%02X', v))
 end

Output:

 1 08 
 2 00 

Code:

 local bt = wordToByteTable(0xFFFF00)
 for i, v in ipairs(bt) do
