Help with formula (revised question)

I asked a similar question earlier. Thank you
everyone who tried helping. However, I'd now
like to revise the data and requirements.
Here is the new data set:

X Y
-- --
0.0 1
0.1 1
0.5 1
0.9 1
1.0 1
1.03 2
1.5 2
1.8 2
2.0 2
2.3 3
3.0 3
3.2 4

X is a positive real number greater than or equal
to zero (or 0.0). Y is an integer as seen in the
second column above.

Can this data be represented with a formula
that only uses either addition, subtraction,
multiplication, division, modulus, or the power (^)
function, or any combination of these?

The function f(x) = x + (0^x) almost works, but
it needs a little bit of tweaking.

If possible, I would like to avoid using any
abs() value functions, or max() functions, or
"if-else" programming logic, or roundup() functions.
I'm curious if I can find a formula that only
uses basic math operators.

I'd appreciate any ideas. Thank you!
