Lua:dwordToByteTable

function dwordToByteTable(Number)

Converts a DWORD (4 bytes) 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 DWORD (4 bytes) only the lower portion of the number will be used.

i.e.: 0xFFFFFFFF00 : 0xFFFFFF00

Examples

Code:

 local bt = dwordToByteTable(0xFFFFFFFF)
 writeBytes('00123ABC', bt)

Code:

 local bt = dwordToByteTable(10)
 for i, v in ipairs(bt) do
   print(i, string.format('%02X', v))
 end

Output:

Code:

 local bt = dwordToByteTable(10.9)
 for i, v in ipairs(bt) do
   print(i, string.format('%02X', v))
 end

Output:

Code:

 local bt = dwordToByteTable(0xFFFFFFFF00)
 for i, v in ipairs(bt) do
   print(i, string.format('%02X', v))
 end

Output:

 1 00 
 2 FF 
 3 FF 
 4 FF
