title: Formulate

abstract: >-

Easy conversions between different styles of expressions. Formulate converts

in either direction between ROOT (TTreeFormula) and numexpr style

expressions, and can also render a parsed expression as plain Python using

NumPy functions. It needs neither ROOT nor numexpr installed, and it knows

the places where the two languages disagree.
