Or, to put it better - a question worth thinking about: how much do we actually depend on search engines?</p> <p>In the age of AI we are being charged pretty much for every query or MCP call. Every web search made by an agent costs tokens, API credits, or a subscription tier. And it adds up quickly, because agents search a <em>lot</em>. But does it need to be this way?</p>https://polgrabia.me/posts/20250312-bigdecimal-why-do-we-need/Wed, 12 Mar 2025 00:20:58 +0200https://polgrabia.me/posts/20250312-bigdecimal-why-do-we-need/<h2 id="why-do-we-need-it">Why do we need it?</h2> <p>This question is the pretty standard one in algorithmic interview questions. So, why do we need it? I think it&rsquo;s fair to ask. The main reason behind this is knowing how floating point numbers are being stored. Usually, you don&rsquo;t need it to use this knowledge otherwise to know &ldquo;solution&rdquo; but it&rsquo;s good to know.</p> <p>The main reason is the precision or rather, the lack of it. In environments where we need to have big numbers very precise like face values and when it&rsquo;s multiplied by exchange ratios, the potential difference can be very signifcant. Therefore potential financial risk can be signifcant, too.</p>https://polgrabia.me/posts/20250225-post1/Tue, 25 Feb 2025 00:00:00 +0200https://polgrabia.me/posts/20250225-post1/<p>Hi, it&rsquo;s my first post.</p> <p>You can find more information about me under the &laquo;about&raquo; page.</p>
