agena >> `The Power of Procedural Programming` 6.3.8 Lookout Mountain, November 07, 2025 - New `mp.power` and the `^` and `**` operators now support exponentiation of unsigned GMP integers. - New `mp.log10` computes the base-10 logarithm of a GMP integer and returns either a GMP integer or an Agena number. - New `mp.ispow2` checks whether its input is a power of two. - `mp.log2` has become 15 percent faster. The function also no longer goes into an infinite loop with negative integers, now returning `undefined` instead. If given `true` as an optional second argument, the function returns a GMP integer instead of an Agena number. - If you pass `true` as the fourth argument to `mp.powm` which conducts modular exponentiation, the function internally calls a GMP function that is intended for cryptographic purposes, where resilience to side-channel attacks is desired. - New `mp.mulm` conducts modular multiplication and new `mp.invm` computes the modular multiplicative inverse. - `mp.inverse` has been deprecated, use `mp.invm` instead. - `mpf.root` is now available in all Debian-based editions. - `mp.powm`, the `/` and `%` operators, `mp.modulus`, `mp.tdiv`, `mp.tdivq`, `mp.tdivr`, `mp.inverse`, `mp.powm` crashed if the modulus or divisor was zero. This has been fixed. The functions and operators now return `undefined` instead. - `mp.tdiv` has been protected against stack corruption. - The `__abs` and `__unm` metamethods implemented in the `mp` package did not store the base to the result, potentially crashing the interpreter in subsequent operations. This bug affected the `abs` and unary minus operators and has been fixed.
