 Operations on `float` variables include a few we've seen before and some new
 ones. Notice here that we mostly use floating-point registers `xmm_`, but

 All our variables so far have had type `int` (integer), but there are limits
 to what you can do with just whole integers. For example, here's the formula

 Write a function to perform this conversion. Some starting points:
 * Reread [the section on variables and registers](https://github.com/akkartik/mu/blob/main/mu.md#variables-registers-and-memory)
   with special attention to the `float` type.
-* Read [the section on floating-point arithmetic](https://github.com/akkartik/mu/blob/main/mu.md#floating-point-arithmetic).
+* Read [the section on fractional arithmetic](https://github.com/akkartik/mu/blob/main/mu.md#fractional-arithmetic).
 * One wrinkle is that the x86 instruction set doesn't permit literal
   fractional arguments. So you'll need to _create_ 1.609 somehow. See the
   section on moving values around under [operations on simple types](https://github.com/akkartik/mu/blob/main/mu.md#operations-on-simple-types).
