Reducing to largest possible unit

[seandenigris]

According to the Chalten paper, reducing should be built-in but doesn't currently seem to work. It seems this used to work... ==10 years * 12 months / 24 months = 5 years== “The model automatically simplifies units”... Anyone know why it was changed?

It looks like it's working. Number>>years is now part of the Pharo Kernel and creates a Duration.
