Agena

Agena is an easy-to-learn procedural programming language suited to be used in scientific, educational, linguistic, and many other applications, including scripting.

• The new function `bytes.shift32` shifts the bits in a 32-bit integer to the left or the right.
• The new function `bytes.rotate32` rotates the bits in a 32-bit integer to the left or the right.
• The new function `bytes.arshift32` performs arithemtic shift of the bits in a 32-bit integer.
• The new function `bytes.extract32` returns the number formed by a given bit field in a 32-bit integer.
• The new function `bytes.replace32` replaces the bits in a bit field of an 32-bit integer with a new one.
• The new functions `bytes.and32`, `bytes.or32` and `bytes.xor32` conduct bitwise-AND, -OR and -XOR operations on one or more 32-bit integers. `bytes.not32` conducts bitwise negation of a 32-bit integer.
• The new functions `bytes.nand32`, `bytes.nor32` and `bytes.xnor32` conduct complementary bitwise-AND, -OR and -XOR operations on one or more 32-bit signed integers.
• `bytes.castdouble` has been removed as it has been identical to `bytes.castint`.
• The 64-bit rotation operators `` did not correctly move bits beyond the 32 bits threshold. This has been fixed.
• `bloom.new` issued confusing error messages with missing arguments. This has been changed.
• Added tips for Linux users to Chapter 2.2 of the Primer and Reference.
• This release has been Valgrind-3.12.0-checked on x86 Linux x86 Raspian Stretch to ensure there are no memory leaks.
