DeciMojo v0.3.0 for Mojo 25.2

DeciMojo v0.3.0 introduces the arbitrary-precision BigDecimal type with comprehensive arithmetic operations, comparisons, and mathematical functions (sqrt, root, log, exp, power). A new tomlmojo package supports test refactoring. Improvements include refined BigUInt constructors, enhanced scale_up_by_power_of_10() functionality, and a critical multiplication bug fix.

⭐️ New

  • Implement the BigDecimal type with unlimited precision arithmetic.
    • Implement basic arithmetic operations for BigDecimal: addition, subtraction, multiplication, division, and modulo.
    • Implement comparison operations for BigDecimal: less than, greater than, equal to, and not equal to.
    • Implement string representation and parsing for BigDecimal.
    • Implement mathematical operations for BigDecimal: sqrt, nroot, log, exp, and power functions.
    • Iimplement rounding functions.
  • Implement a simple TOML parser as package tomlmojo to refactor tests (PR #63).

🦋 Changed

  • Refine the constructors of BigUInt (PR #64).
  • Improve the method BigUInt.scale_up_by_power_of_10() (PR #72).

🛠️ Fixed

  • Fix a bug in BigUInt multiplication where the calcualtion of carry is mistakenly skipped if a word of x2 is zero (PR #70).
