How to get a float value the pointer points to?
- by aleluja
Hello,
In my app, i've created the TList type list where i store the pointers to 1 string and 2 float(real) values for every 3 items.
aList.Add(@sName); //string
aList.Add(@x1); //float
aList.Add(@x2); //float
Then, i want to get the values out from the list, but i could only do that for string
sStr := string(lList.items[i]);
But i couldn't get the float values as a := real(lList...) will result in an invalid typecast error.
So what do i do to get the float values?
Of course i have a question if that string casting will actually give me the string value. I'm not good at pointer stuff so i don't know how to do it.
