* Cached function to compute powers of 10 for Decimal.js operations.
* This cache significantly reduces overhead in ComputeExponent and ToRawFixed
* by memoizing expensive Decimal.pow(10, n) calculations.
*
* Common exponents (e.g., -20 to 20) are used repeatedly in number formatting,
* so caching provides substantial performance benefits.
*
* @param exponent - Can be a number or Decimal. If Decimal, it will be converted to string for cache key.
