IROX-STATS
Various mathematical and statistics utilities
No-STD support:
- By default, makes use of
allocin many places.
Features:
- std: adds interactions with the standard library & operating system.
- miniz: adds deflate compression/decompression support
- emath: adds conversion to/from emath primitives
