Useful 100%x !

[colin9876]

I really like the way B4a can use 100%x, 100%y to find the screen res rather than having to do a system call.

What Im wondering is how 100%x is stored internally?
1) If it involves a system call eachtime its used am I better to have one line saying fullx=100% (for example) then use my fullx variable if Im using it lots of times?

2) I see its possible to use other values like 1%x, 25%x,50%x etc ??
If I have a variable e.g. myx=rnd(0,100)
lets say myx=59, how can I then say 59%x
will myx%x work????

Using the percentage unit is a shorthand for calling:
PerXToCurrent and PerYToCurrent: Basic4android - Core
In almost all cases there is no reason to store it locally. And also remember that these values can change if the user rotates the screen.

2) You can use these functions when working with variables.
