Expand description
The VRCP / VRSQ reciprocal ROMs.
512 entries each, generated by exact integer arithmetic rather than
stored as literals — a deliberate departure from docs/rsp.md’s “data, not
a formula” rule, argued and bounded in accuracy ledger C-31. The short
version: the rule guards against approximation, and these constructions
have no rounding freedom, so they reproduce the ROM rather than estimating
it. The construction is ares’s (ISC).
Statics§
- INVERSE_
SQUARE_ ROOT - The inverse-square-root ROM, likewise built at compile time.
- RECIPROCAL
- The reciprocal ROM, built at compile time.
Functions§
- inverse_
square_ root - The inverse-square-root ROM entry for
index. - reciprocal
- The reciprocal ROM entry for
index.
