Get the needed subpart of the string (1.3) and cast it to a float or double
1.3 can not be an int.

Maybe i did not understand the question right. Dont know what you mean with "relative string"

the string is a screen relative percentage like in the example 1.3%x... if I put this into the map without the quotes it works and gets converted to an integer screen value... but with the quotes I get an error... so i'm guessing I will have that error once I read that value from a file ( not yet implemented)

Sadly b4a does not have a "eval"

Write the real int behind the relative value into the file and read the int back instead of a string.

B4X:

log(1.3%x)

You can write the int value to a file. for the rest you can use YOUR brain

Lol.... I found a workaround... Not in parsing but in my way of making my calculations

Hi @Cableguy is this for what I think it is
Just store the value you want to use and then multiply it by 1%x or 1%y as required.
