This PR exposes the
num_to_roughnum
function on the Pyret runtime.This function is heavily used in the TensorFlow addition (see brownplt/code.pyret.org#287), but should be relatively easy to swap out if there are better alternatives. There might be a better way to create Roughnums from a JavaScript library that I'm missing, so let me know if this is unnecessary.
