Continued

Continued is a simple library for representing and operating on numbers represented as continued fractions.

Features

• Conversion from a plethora of representations to continued fractions

  • int
  • float
  • decimal.Decimal
  • fractions.Fraction and numbers.Rational

• Basic arithmetic: addition, subtraction, multiplication, division

• Popular irrational and transcendental identities, to arbitrary (infinite) precision

  • e (Euler's number)
  • |pgr|
  • |phgr| (the Golden Ratio)

• Arbitrary-precision quadratic surds

Bugs

Plenty.

• sqrt(2) * sqrt(2) goes into an infinite loop, as does any other operation with an arbitrary string of 0.

Some enhancements are planned.

• Surds should permit the form (a + sqrt(b))/c without an extra pair of combination generators.
• Trigonometric operators.
• Radix-based decoding.
