BQN is aimed at existing and aspiring APL-family programmers, and using it requires a solid understanding of functions and multidimensional arrays. However, because of its focus on providing simple, consistent, and powerful array operations, BQN should also be a good language for learning array programming and building stronger array intuition.</p> <p>BQN maintains many of the ideas that made APL\360 revolutionary in 1966:</p> <ul> @@ -29,7 +29,7 @@ <pre> <span class='Function'>⊑+</span><span class='Modifier'>`</span><span class='Modifier2'>∘</span><span class='Function'>⌽</span><span class='Modifier2'>⍟</span><span class='Number'>12</span><span class='Function'>↕</span><span class='Number'>2</span> <span class='Comment'># The 12th Fibonacci number </span>144 </pre> -<p>For longer samples, you can <a href="https://github.com/mlochbaum/BQN/blob/master/c.bqn">gaze into the abyss</a> that is the (incomplete) self-hosted compiler, or take a look at the friendlier <a href="https://github.com/mlochbaum/BQN/blob/master/md.bqn">markdown processor</a> used to format and highlight documentation files.

However, it discards many of the complications of traditional APL <a href="https://aplwiki.com/wiki/Array_model">array models</a>. Unlike in APL, non-array data is possible, and common: numbers, characters, and functions are not arrays (see the full list of <a href="#types">types</a> below). This avoids some difficulties that show up when trying to treat scalar arrays as the fundamental unit; in particular, there is no "floating" so a value is always different from a scalar array that contains it. This system has been <a href="https://dl.acm.org/doi/abs/10.1145/586656.586663">proposed</a> in APL's past under the name <strong>based array theory</strong>.</p> <p>Currently, the intention is that arrays will not have prototypes, so that all empty arrays of the same shape behave identically. Different elements of an array should not influence each other. While some APLs force numbers placed in the same array to a common representation, which may have different precision properties, BQN will enforce 64-bit floating-point precision, and only use representations or methods compatible with it (for example, integers up to 32 bits).</p> |
