To facilitate move developers with a more comprehensive standard library.

Specification

Section titled “Specification”
  • Add FixedPoint64 as a more precise counterpart to FixedPoint32, with 18 digits precision and covering numbers between 0 and 10^18.
  • Add sqrt, exp, log, log2, floor_log2, mul_div to the library as standard functions.
  • Add additional inline functions for standard algorithms to the vector library. Namely for_each_reverse, rotate, partition, foldr, stable_partition and trim.
  • Add upsert to simple table allowing to update existing keys or insert new key.
