There are two motivations for this:
1. It improves readability to my eyes
2. Using nested min() calls results in a shadowed _min1 variable,
which is a bit untidy. Sparse complained about this.
I have also replaced (size_t)64 with a variable of type size_t and value 64.
This also improves readability to my eyes.
