What variable type to use for decimal numbers

ROOT
1

Hello all,

I am trying to read data from a txt file into a tree. My txt file contains numbers such as -1.206.

My question is: What variable type do I need to specify to the branch descriptor in the tree->ReadFile command in order to be able to read such numbers.

Thank you

I think float is enough ("/F")

Cheers,
