Hello,
I have this code:

Code:

local i=readInteger(baseAddress+iOffset)
if i<0 and i>=(0-iTolerance) then e.DisplayMethod = 'dtSignedInteger'
elseif i>iTolerance then e.DisplayMethod = 'dtHexadecimal'
end

iTolerance is set to 100.
Negative integers between 0 and negative tolerance are displayed as HEX.
I must be missing something banally simple Very Happy

Any ideas?

Thanks!

Here's the point you missed:

Code:

i = -1 --> readInteger(address) = 4294967295

-- use

i = -1 --> readInteger(address, true) = -1

Example:

Code:

iTolerance = 100
addr = "30C11A44" -- ex..
local i=readInteger(addr,true)
print(i)
if i>=0 and i<=iTolerance then print('dtSignedInteger')
else print('dtHexadecimal')
end

-- res <0 ~ 100> = dtSignedInteger /// >0 ~ 100< = dtHexadecimal
-- i = -1 --> dtHexadecimal
-- i = 99 --> dtSignedInteger
-- i = 100 --> dtSignedInteger
-- i = 101 --> dtHexadecimal

-- or

Code:

iTolerance = 100
iTolerance1 = 1-iTolerance
--print(iTolerance1)
addr = "30C11A44"
local i=readInteger(addr,true)
print(i)

if i >= iTolerance1 and i <= iTolerance then print('dtSignedInteger')
else print('dtHexadecimal')
end

-- res <-100 ~ 100> = dtSignedInteger /// >-100 ~ 100< = dtHexadecimal
-- i = -2 --> dtSignedInteger
-- i = -100 --> dtSignedInteger
-- i = -101 --> dtHexadecimal
-- i = 10 --> dtSignedInteger
-- i = 100 --> dtSignedInteger
-- i = 101 --> dtHexadecimal

Good luck .. Smile

readInteger(address) : Reads a 32-bit integer from the specified address

I did not think it had a hidden a parameter; thanks, works now!
