Ratio division looks wrong

[etiago]

In the following line:

algorithmica/content/english/hpc/arithmetic/float.md

Line 41 in ed1945c

r operator/(r a, r b) { return {a.x * b.x, a.y * b.y}; }

Instead of:

r operator/(r a, r b) { return {a.x * b.x, a.y * b.y}; }

I think this is showing the division of two ratios and it should show:

r operator/(r a, r b) { return {a.x * b.y, a.y * b.x}; }

More generally, the division shows exactly the same as the multiplication which doesn't seem to make sense.
