Chris Barker,
If isclose() function is to be part of the standard library I would
ask that the rel_tol and abs_tol both accept -log10 scaled values:
Instead of
isclose(a, b, reltol=1e-9, abstol=0.0)
we have
isclose(a, b, reltol=9, abstol=-INF)
rel_tol can be understood in terms of number of significant digits.abs_tol is understood in terms of fixed decimal digits.
Thanks for noticing the ubiquitous need for such function.
