perf(patch): O(1) fast path for pow(10, n) via lookup table#1
Merged
Conversation
pow(10, n) now uses _pow10Table directly instead of n-1 repeated multiplications through Int128 banker's rounding division. Benchmark: 1.96 ns (52 instructions) vs 48 ns (613 instructions) for the general path — 25x faster. Adds 5 test cases covering positive/negative exponents, overflow, sub-precision, and parity with the general path. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Description
pow(10, n)now uses_pow10Tabledirectly instead of n-1 repeated multiplications through Int128 banker's rounding division. Only triggers for base 10; all other bases use the existing general path unchanged.How Has This Been Tested?
Benchmark: 1.96 ns (52 instructions) vs 48 ns (613 instructions) for the general path — 25x faster.
