For future reference, you can find out if an alias is available for a particular package by running

In [1]: pkg2alias( '@stdlib/number/float64/base/to-float32' )
'base.float64ToFloat32'

This way you don't have to explicitly require packages which are already available.

Okay, I tried this just now, the alias is already available. Thanks for sharing!
