Hi guys,

Code:

function string.trimstart(s, c)
if (not c) then c = ' '; end
s = string.reverse(s);
s = string.trimend(s, c);
return string.reverse(s);
end

-- desc: Trims the end of a string for whitespace.
function string.trimend(s, c)
if (not c) then c = ' '; end
if (string.sub(s, -1) == c) then
s = string.sub(s, 0, -2);
s = string.trimend(s, c);
end
return s;
end

-- desc: Trims a string of whitespace.
function string.trim(s, c)
if (not c) then c = ' '; end
s = string.trimstart(s, c);
s = string.trimend(s, c);
return s;
end

-- desc: Converts the given string to a hex array string.
function str2hexstr(str)
local ret = '';
for x = 1, #str do
-- Pull a single character from the string..
local val = str:sub(x, x);
-- Convert the character to hex..
local c = string.byte(val);
-- Append to the result..
ret = ret .. string.format('%02X ', c);
end
-- Trim and return the result..
return ret:trim();
end

---- Test
input= 1 --- get input value using CEEdit, identifying as 'String Value"
input=str2hexstr(input)
print(input)
------- result = 31 (as AOB) or AOB string ?

------- Use DEC_HEX
function DEC_HEX(IN)
local B,K,OUT,I,D=16,"0123456789ABCDEF","",0
while IN>0 do
I=I+1
IN,D=math.floor(IN/B),math.mod(IN,B)+1
OUT=string.sub(K,D,D)..OUT
end
return OUT
end

a=DEC_HEX(1)
print(a)

1

I know for number = 1 (pushbyte 1), will give AOB = 24 01
I have search for some lua references to convert number to AOB.
Is there any function to do that ?

Thank and regard

Zanzer

Code:

wordToByteTable(number): {} - Converts a word to a bytetable
dwordToByteTable(number): {} - Converts a dword to a bytetable
qwordToByteTable(number): {} - Converts a qword to a bytetable
floatToByteTable(number): {} - Converts a float to a bytetable
doubleToByteTable(number): {} - Converts a double to a bytetable
stringToByteTable(string): {} - Converts a string to a bytetable
wideStringToByteTable(string): {} - Converts a string to a widestring and converts that to a bytetable

string.format("%X", number)

Thanks Zanzer,

Test

Code:

a=1
print(unpack(wordToByteTable(a)))
print(unpack(dwordToByteTable(a)))
print(unpack(qwordToByteTable(a)))
print(unpack(floatToByteTable(a)))
print(unpack(doubleToByteTable(a)))
print(unpack(stringToByteTable(tostring(a))))
print(unpack(wideStringToByteTable(tostring(a))))
print(string.format("%X", a))

1 0
1 0 0 0
1 0 0 0 0 0 0 0
0 0 128 63
0 0 0 0 0 0 240 63

I just looking for some references to get understand from where pushbyte 1 refer as 24 01 in AVM2 opcode
