Bumps [bigdecimal](https://github.com/akubera/bigdecimal-rs) from 0.4.8 to 0.4.9. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/akubera/bigdecimal-rs/releases";>bigdecimal's releases</a>.</em></p> <blockquote> <h2>v0.4.9</h2> <h2>Changes</h2> <ul> <li> <p>Add methods <code>BigDecimal::{powi, powi_with_context}</code> for raising a decimal to a i64 power</p> <ul> <li>the <code>powi</code> uses Default Context</li> </ul> </li> <li> <p>Add methods <code>BigDecimal::mul_with_context</code> for efficient multiplication to fixed precision</p> <ul> <li>uses precision and rounding-mode in the Context</li> </ul> </li> <li> <p>Add method <code>BigDecimal::decimal_digit_count</code>, returning number of decimal digits (i.e. precision) of the number</p> </li> <li> <p>Add method <code>BigDecimal::order_of_magnitude</code>, returning position of most significant digit of this decimal</p> </li> <li> <p>Add method <code>BigDecimal::is_one_quickcheck</code>, returning <code>Option<bool></code> indicating if the value is <code>1.0</code> if it can be calculated without allocating, or None if too large</p> <ul> <li>Replaced <code>is_one</code> in multiplication methods when used for optimizations <ul> <li>Should test if that actually speeds it up</li> </ul> </li> <li>Eg value <code>1.00000000000000000000000000000000000000000</code> is stored internally as <code>[4870020673419870208, 16114848830623546549, 293] E -41</code> and it's hard to tell this is equivalent to 1</li> </ul> </li> <li> <p>Add optimizations to inverse</p> <ul> <li>small powers of ten will simply flip their scale <code>1/10e-5 -> 10e5</code></li> <li>convert to f64 to make initial guess when before iterative algorithm</li> </ul> </li> <li> <p>Add <code>Context::invert(&self, BigDecimalRef)</code>, equivalent to <code>BigDecimal::inverse_with_context(&self, &ctx)</code></p> <ul> <li>Still has a bug where rounding ignores sign, affecting floor/ceiling modes</li> </ul> </li> </ul> </blockquote> </details> <details> <summary>Commits</summary> <ul> <li><a href="https://github.com/akubera/bigdecimal-rs/commit/51a1fbadd1c42eab283a56f26f7eb74a1fa71586";><code>51a1fba</code></a> v0.4.9</li> <li><a href="https://github.com/akubera/bigdecimal-rs/commit/deff05952c735fe6fb84244f6ac74bc296ced8d9";><code>deff059</code></a> Version 0.4.9</li> <li><a href="https://github.com/akubera/bigdecimal-rs/commit/bdab3a7f232b955b7e21663b54cdaee71bce2cb7";><code>bdab3a7</code></a> Remove blanket allow(dead_code)</li> <li><a href="https://github.com/akubera/bigdecimal-rs/commit/f2cf07da32170442b872fddd1ba34ea5aaf5ba02";><code>f2cf07d</code></a> Merge implementation of powi into trunk</li> <li><a href="https://github.com/akubera/bigdecimal-rs/commit/9694c91ffe3d449bd1a9039692296a8320534def";><code>9694c91</code></a> Add more pow test cases</li> <li><a href="https://github.com/akubera/bigdecimal-rs/commit/a69eabe399421c0cc939aec31add55db61a9e761";><code>a69eabe</code></a> Clear <code>tmp</code> vector after use in DigitVec::from_biguint_using_tmp</li> <li><a href="https://github.com/akubera/bigdecimal-rs/commit/a1237bd7e661542c65549587326dc0edba39f5e0";><code>a1237bd</code></a> Invert before calling pow_u64</li> <li><a href="https://github.com/akubera/bigdecimal-rs/commit/372c09479668cefc750f11dcacbd1c9071ffc3fb";><code>372c094</code></a> Add new_truncating constructor for Context</li> <li><a href="https://github.com/akubera/bigdecimal-rs/commit/f9e8435b9c10f0f724f126b299845806c209dad3";><code>f9e8435</code></a> Split BigDecimalRef conversions into separate function for multiply_decimal_w...</li> <li><a href="https://github.com/akubera/bigdecimal-rs/commit/555c6f31e3ca6ce30d65430cdc6dc6beda90d4d1";><code>555c6f3</code></a> Add function get_power_of_ten_u64 to arithmetic::decimal</li> <li>Additional commits viewable in <a href="https://github.com/akubera/bigdecimal-rs/compare/v0.4.8...v0.4.9";>compare view</a></li> </ul> </details> <br /> [](https://docs.github.com/en/github/managing-security-vulnerabilities/about-dependabot-security-updates#about-compatibility-scores) Dependabot will resolve any conflicts with this PR as long as you don't alter it yourself.
