mariadb-numeric-functions

MariaDB numeric and math functions — rounding/truncation (ROUND, the TRUNCATE function vs the TRUNCATE TABLE statement, FLOOR, CEILING, SIGN, ABS), integer-vs-decimal division (the DIV operator vs /, MOD / %), powers and logs (POW/POWER, SQRT, EXP, LN, LOG, LOG2, LOG10), trigonometry (SIN, COS, TAN, ASIN, ACOS, ATAN, ATAN2, COT, PI, DEGREES, RADIANS), randomness (RAND, seeded RAND(N)), base conversion (CONV, OCT, BIN, HEX), checksums (CRC32, CRC32C), and number formatting (FORMAT). Use when writing SQL that does arithmetic, rounding, base conversion, or random sampling in MariaDB — especially where exact-vs-approximate types or division-by-zero behavior matter.
