In python to get the smallest positive usable number for a float you can use: numpy.finfo(float).tiny Julia implement the function eps, but I don’t see nothing similar to tiny. Thanks.

As an update to this thread, looks like the new function is floatmin: help?> floatmin search: floatmin floatmax float flatten Float16 Float32 Float64 findmin Cfloat floatmin(T = Float64) Return the smallest positive normal number representable by the floating-point type T. On a x86_64: ju…

Hmm, the numpy docs really do say that.

More precisely, this is the smallest magnitude normal floating point number, which is available in Julia via realmin(Float64).
