How to extract float number from a string?

[Ultima2]

$number = 2.3
$number1 = 1.5
$ok = ""&$number&", "&$number1&"j"

How do I extract $number and $number1 from the string and set them separately to float point numbers again?

I tried the help file but couldnt find anything that could help me

Hi,

For extract it you can use string functions :

StringSplit

StringLeft

StringRight

StringTrimLeft

StringTrimRight

StringReplace

........

Could you post an example please, that doesn't really help me because im still a newbie D:

Could you post an example please, that doesn't really help me because im still a newbie D:

$String="Number 1.5 and Number 2"
$Number1=StringLeft(StringTrimLeft($String,7),3)
$Number2=StringRight($String,1)
Msgbox(64,"",$Number1&" and "&$Number2)

You can check this functions on autoit helpfile with F1 key in SciTE

Ok thank you very much, but what if you dont know the exact digit of the number, like log(3).

Like

$x = log(3)
$z = log(2)
$ok = ""&$x&", "&$z&""

How would you extract the entire value of $x and $z from the string? Thanks

Do you want to search all numbers in a log ? (1-9)

Try this

#include <Array.au3>

$x = log(3)
$z = log(2)
$ok = ""&$x&", "&$z&""

;~ $number = 2.3
;~ $number1 = 1.5
;~ $ok = ""&$number&", "&$number1&"j"

ConsoleWrite($ok)


$new = StringRegExpReplace($ok,"[^0-9.\s]","")
$array = StringSplit($new, " ")
_ArrayDisplay($array)

No I just want to know how to extract a number from a string. How do I extract a number from a string if I dont know the exact length of the number. like sqrt(5).

if you don't length of the number you have to search it... look at StringRegExp , Stringinstr

I cant understand the help file. They're like written for people with 180+ IQ. Like for the code

$x = log(3)
$z = log(2)
$ok = ""&$x&", "&$z&""

I have a string "$x, $z". How do I extract $x and $z from the string. I cant use the method you showed me earlier because it only works if I know the exact length of log(3) and log(2).

$number = 2.3
$number1 = 1.5
$ok = ""&$number&", "&$number1&"j"

ConsoleWrite($ok & @CR)

$new = StringRegExpReplace($ok,"[^0-9.\s]","")
$array = StringSplit($new, " ")
ConsoleWrite($array[1] & " " & $array[2] & @CR)

$x = log(3)
$z = log(2)
$ok = ""&$x&", "&$z&""

ConsoleWrite($ok & @CR)

$new = StringRegExpReplace($ok,"[^0-9.\s]","")
$array = StringSplit($new, " ")
ConsoleWrite("x=" & $array[1] & " z=" & $array[2] & @CR)

If this isn't what you asked for please explain how you mean.

$x = 3.14

$z = 2.6243563

$ok = $x & "," & $z

$ss = StringSplit($ok, ",")

; $ss is [2, "3.14", "2.6243563"]

$newx = Number($ss[1])

$newy = Number($ss[2])

Thank you. I'll try to read the help file again. The help file is like written in another language, I only understand like 2% of it
