Preserving uncommitted work found in an open worktree during a worktree audit. Float + previously fell through to string concat (segfault); -, *, /, % operated on raw IEEE-754 bit patterns as integers (garbage results). Floats are now tracked via a __float_names typed-binding set (parallel to the existing int-tracking scheme) and arithmetic is emitted as real C double ops. Also fixes math_log, which was wrongly aliased to natural log (duplicating math_ln) — now uses log10 — and adds the missing <math.h> include. Rebuilt elc binary included.

Float + previously fell through to string concat (segfault); -, *, /, %
operated on raw IEEE-754 bit patterns as integers (garbage results). Floats
are now tracked via a __float_names typed-binding set (parallel to the
existing int-tracking scheme) and arithmetic is emitted as real C double
ops.

Also fixes math_log, which was wrongly aliased to natural log (duplicating
math_ln) — now uses log10 — and adds the missing <math.h> include. Rebuilt
elc binary included.
