That's ok. You're not the only one. And David seems to be a little

A popular myth, but debunked by Denis Richie himself.

it does translate perfectly into PDP-11 assembler.
However, there still seem to be some debate about the real vs. double 
floating point types as related to the PDP-11 architecture.
