Android Question String to Number or add decimal to string

[Jan Van Gastel]

All,

I have a code which generates strings with info from a telnet socket.
This part is working.

I have as string with a "number" in it, for example 201.
Now in real lieve this value is 20.1 , so I need to add a decimal to it.

2 options:

- Can I convert the string to a double, float... ?
- Can I add a decimal to the string ? 201 -> 20.1 ?

 

[Mahares]

Something like one of these two:

Log(NumberFormat(201/10,1,1))    'displays: 20.1
Log($"${NumberFormat(201/10,1,1)}"$)   'displays: 20.1

 

[Jan Van Gastel]

Yes, but then I already need a double.
The "201" is in a string, so I need to convert the string to a number OR I need to put a decimal in between.

, so I need to convert the string to a number

the number for THIS string is 201!

You could Looop through the string and check every char in the string if it is a number. if so you could add it to another string linke this:

dim number as string

For each c as Char in String
If Isnumber(c) then
number = number & c
end if
Next

You could Looop

it will result in the number 201 too but not 20.1

 

[Jan Van Gastel]

Yes, but this gives an error:

Dim String1 as string = "201"
Dim String2 as string

String2 = NumberFormat(String1/10,1,1))

The above code will work after you remove the extra closing parenthesis.

in B4J this works fine

Dim str1,str2 As String
str1="201"
str2=str1/10
Log(str2)

and output 20.1
