#3179 new Bug

Number failure with lower case hex

Reported by: czardas Owned by:
Milestone: Component: AutoIt
Version: 3.3.14.2 Severity: None
Keywords: Number Hexadecimal Cc:

Description

The interpreter is not fussy when it comes to lower case hexadecimal strings representing integers. The Number function seems to disregard this fact. Either this is a bug or it represents an inconsistency, which seems undesirable from my perspective.

ConsoleWrite('Execute()' & @LF) ; Integers are not case sensitive in AutoIt
ConsoleWrite(Execute('0x07AFBFEF4FF55FF0') & @LF) ; Uppercase [success]
ConsoleWrite(Execute('0x07afbfef4ff55ff0') & @LF) ; Lowercase [success]
ConsoleWrite(Execute('0x07aFbFeF4FF55FF0') & @LF) ; Mixture [success]

ConsoleWrite(@LF & 'Number()' & @LF) ; Number() appears to be case sensitive
ConsoleWrite(Number('0x07AFBFEF4FF55FF0') & @LF) ; Uppercase [success]
ConsoleWrite(Number('0x07afbfef4ff55ff0') & @LF) ; Lowercase [failure] ???
ConsoleWrite(Number('0x07aFbFeF4FF55FF0') & @LF) ; Mixture [failure] ???

I forgot to mention that there is more information on the private MVP forum : https://www.autoitscript.com/forum/topic/178945-conversion-to-number/#comment-1284838
It is $NUMBER_AUTO flag which is not behaving the same way the interpreter does.

After getting nowhere fast, an angel came and whispered in my ear:

'The issue has nothing to do with lowercase string representation of binary data. The real issue is the letter "e", which is treated as a moniker (scientific e notation) for floats.'

ConsoleWrite(Number('0x07afbfaf4ff55ff0') & @LF)

This angel was slightly drunk: in fact, Number has two distinct bugs, both related to case sensivity.

First it interprets '1E2' and '1e2' differently, '1E2' being converted to 1 (wrong) instead of 100.
Second, it interprets any 'e' digit of hex values having more than 8 hex digits case-sensitively, with for instance '0x0000001E2' --> 482 (correct) but '0x0000001e2' --> 0

ConsoleWrite("Testing 1E2 --> ")
ConsoleWrite(1E2 & @LF)
ConsoleWrite("Testing 1e2 --> ")
ConsoleWrite(1e2 & @LF)
ConsoleWrite("Testing 0x1E2 --> ")
ConsoleWrite(0x1E2 & @LF)
ConsoleWrite("Testing 0x1e2 --> ")
ConsoleWrite(0x1e2 & @LF)
ConsoleWrite("Testing 0x0000001E2 --> ")
ConsoleWrite(0x0000001E2 & @LF)
ConsoleWrite("Testing 0x0000001e2 --> ")
ConsoleWrite(0x0000001e2 & @LF)

ConsoleWrite(@LF)

ConsoleWrite("Testing Execute(1E2) --> ")
ConsoleWrite(Execute(1E2) & @LF)
ConsoleWrite("Testing " & "Execute(1e2) --> ")
ConsoleWrite(Execute(1e2) & @LF)
ConsoleWrite("Testing Execute('1E2') --> ")
ConsoleWrite(Execute('0x1E2') & @LF)
ConsoleWrite("Testing Execute('1e2') --> ")
ConsoleWrite(Execute('0x1e2') & @LF)
ConsoleWrite("Testing Execute('0x0000001E2') --> ")
ConsoleWrite(Execute('0x0000001E2') & @LF)
ConsoleWrite("Testing Execute('0x0000001e2') --> ")
ConsoleWrite(Execute('0x0000001e2') & @LF)

ConsoleWrite(@LF)

ConsoleWrite("Testing Number('1E2') --> ")
ConsoleWrite(Number('1E2') & @LF) ; Uppercase [failure]
ConsoleWrite("Testing Number('1e2') --> ")
ConsoleWrite(Number('1e2') & @LF) ; Lowercase [success]
ConsoleWrite("Testing Number('0x1E2') -- > ")
ConsoleWrite(Number('0x1E2') & @LF)
ConsoleWrite("Testing Number('0x1e2') -- > ")
ConsoleWrite(Number('0x1e2') & @LF)
ConsoleWrite("Testing Number('0x000001E2') --> " )
ConsoleWrite(Number('0x000001E2') & @LF)
ConsoleWrite("Testing Number('0x000001e2') --> " )
ConsoleWrite(Number('0x000001e2') & @LF)
ConsoleWrite("Testing Number('0x0000001E2') --> " )
ConsoleWrite(Number('0x0000001E2') & @LF) ; Uppercase [success]
ConsoleWrite("Testing Number('0x0000001e2') --> " )
ConsoleWrite(Number('0x0000001e2') & @LF) ; Lowercase [failure]
ConsoleWrite("Testing Number('0x0000001F2') --> " )
ConsoleWrite(Number('0x0000001F2') & @LF)
ConsoleWrite("Testing Number('0x0000001f2') --> " )
ConsoleWrite(Number('0x0000001f2') & @LF)
