  strlen() is a float function.

  There's a good and logical reason for calling it a float function (and
you should know it without me telling it).
  The reason for calling it a float function according to its return value
type is that it can be used anywhere a float is expected. In the same
way a vector function can be used anywhere a vector is expected.

  For example, in the definition of a sphere object the first parameter
is a vector. You can use a vector literal, a vector identifier or a
vector function there. The second parameter is a float. This means that
you can use a float literal, a float identifier or a float function there.
(Of course you can also use expressions which result in a float/vector or
can be promoted to it.)

  So naming and categorizing functions by their return value is not only
logical but it's actualy a categorization by purpose: Float functions are
those which can be used anywhere a float value is expected.
