You can find them in binding/expression classes related to Number:
DoubleExpression, FloatExpression, IntegerExpression, LongExpression
The base class is NumberExpression. There are several overloaded methods to support work with both Observable objects and constants.

Double > Float > Long > Integer
Both operands are checked according to ...
