floor function

Hello,

in root, we can have the integer par of a float number by doing something like this

(int) 3.14
==>3

floor(3.14)
==>3

but how to do the same within a Draw(), a Project() or a Scan() command ?

i mean, let's assume

mytree.Scan("myfloat_leaf")

makes a scan values of the leaf within the tree (actually, i don't know if the word leaf is the good word, anyway)

then
mytree.Scan("floor(myfloat_leaf)")

doesn't work

nor

mytree.Scan("(int)(myfloat_leaf)")

in a more general way, is it possible to do something like

mytree.Scan("complex_function(my_leaf)")
