I gave up. Instead I've started writing my own IEEE quadruple routines. A big job, but one of the reasons I wanted to write my own calculator firmware was to learn about computer arithmetic, so I'm getting what I wished for!

I've finished multiplication, which is one of the easier routines. The most time consuming part was learning the ARM assembly instructions.
