Agena overview

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

What's new in version 7.4.1

Added: the new functions `dd.log2` and `dd.log10` which for a given double-to-double number compute the base-2 and base-10 logarithms, respectively.
The `antilog2` and `antilog10` operators now support double-to-double numbers, computing 2^x and 10^x, respectively.
The `^` exponentiation operator now accepts a double-to-double number as the power. The power can represent a fractional value. Example:
> dd.two^dd.Pi:

8.8249778270762871 (5.3972757612210241e-016)
Added: the new constant `dd.sixteen` for 16.
New: `dd.isdd` checks whether all its arguments are double-to-double numbers and returns a Boolean.
New: `dd.checkdd` checks whether all its arguments are double-to-double numbers and issues an error otherwise.
When given a double-to-double number, `dd.new` simply returns it instead of creating an error.
New: `dd.get` returns both the high part and the low part of a double-to-double number.
All arithmetic `dd` package functions now accpet both double-to-double numbers and standard Agena numbers.
`unimath` package functions now accept double-to-double numbers. Example:
> unimath.zeroin(<: x -> sin(x) :>, dd.three, dd.four):

3.1415926535897931 (1.2246467991473532e-016)
`astro.locate` can now better find places in Linux, macOS and Solaris if their names include multibyte UTF-8 characters or diacritics and ligatures.
The function now also allows to pass a user-defined comparison function and specific codepages and better copes with wildcards. See Chapter 11.9 for details. Example:
> astro.locate('Düsseldorf*', 'DE',

> finder = <: x, y -> x = y :>, codepages = [850, 852]):

[[country ~ DE, elevation ~ 45, latitude ~ 51.22172, location ~ Düsseldorf,

longitude ~ 6.77616, population ~ 620523, timezone ~ Europe/Bonn],

[country ~ DE, elevation ~ 43, latitude ~ 51.23812, location ~ Düsseldorf-Pempelfort,

longitude ~ 6.78678, population ~ 28941, timezone ~ Europe/Bonn]]
