Alexander Whitestone	d467348820	burn: Implement spellf() full number formatting (P0 #18 ) - Fixed floating-point precision bug: numbers >= 1e54 now use string-based chunking (toExponential digit extraction) instead of Math.pow division, which drifts beyond ~54 bits of precision - Integrated into fmt(): numbers at undecillion+ scale (10^36) automatically switch from abbreviated form ('1.0UDc') to spelled-out words ('one undecillion') - Verified: spellf() correctly handles 0 through 10^303 (centillion) - All 320 place value names from NUMBER_NAMES array work correctly The educational effect: when resources hit cosmic scales, digits become meaningless but NAMES give them soul.	2026-04-09 19:29:07 -04:00
