NOOB QUESTION, string to expression

[7121]

Basically here's what i did, i think i posted in the past about this but it didn't make sense.

Here's how it goes.

Here is what was copied,

2 + 4 =

$string = Clipget()

$data = StringRegExp( $string, "=", "" )

this is where i'm lost.

it's still a string rather than expression, what should i do to turn it into one?

so that when i do Msgbox

it won't come out as 2 + 4, but 6 instead.

In addition, what happens if let's say this comes up, 2², or 3². How how i change that into a 2^2 or 3^2 for a string (which i'll switch later on expression anyways)

Here you go,

$sTEXT = '2 + 4 ='
$aTMP = StringRegExp($sTEXT,"([0-9]{1,9}) [+] ([0-9]{1,9})",1)
$sRESULT = $aTMP[0] + $aTMP[1]

MsgBox(0,'RESULT',$sRESULT)

Another way:

$sTEXT = '2 + 4'

$aTMP = StringRegExp($sTEXT, "\d{1,}\s?\+\s?\d{1,}", 1)
If @error Then Exit

$sRESULT = Execute($aTMP[0])

MsgBox(0, 'RESULT', $sRESULT)

so wait, how'd u turn the string from the clipobard into an expression o_0???

And another way.

$aTMP = '(12/4  + 3²)*2 ='

ClipPut($aTMP)

$sTEXT = ClipGet()

; Using ² equal to ASCII 0xB2 
$aTMP = StringRegExpReplace(StringRegExpReplace(StringRegExpReplace($sTEXT, _
                                    "(\xB2)", "^2"), "(\xB3)", "^3"), "=", "")

MsgBox(0, 'RESULT', $sTEXT & " " & Execute($aTMP))

Lookup the Execute() function in help. (Execute an expression.)
