##
# Constants

System.Math.i     # square root of -1
System.Math.PI    # 5 decimal points (same as `System.Math.PI_to(5)`, but only calculated once)
System.Math.PI_to # lambda that calculates a decimal to `n` decimal points


##
# Real Numbers

System.Integer  #=> 1
System.Decimal  #=> 3.14
System.Rational #=> 2 / 3

# would love to implement division in such a way that if the number can
# divide evenly, it just returns the integer, otherwise a rational


##
# Imaginary Numbers
#   access the dynamic property `i` on real numbers for their imaginary counterparts
#   (same as multiplying the real number by System.Math.i)

System.Integer  #=> 1.i
System.Decimal  #=> 3.14.i
System.Rational #=> (2 / 3).i


##
# Complex Numbers
#   literal syntax is <real, imaginary>

System.Complex #=> <42, 3.i>
