NumberTypes

Includes classes defining extra number types of Decimal, WeightedNumber, and Fraction.

Decimal

decimal = Decimal(1, 4)
decimal = Decimal(1, "04")
decimal = Decimal("1", 4)
decimal = Decimal("1", "342")

# A Decimal has two main parts, the integeral and fractional (left and right side of the decimal point).
# Note that when creating a Decimal, the inputs can accept integers, or strings to allow for leading zeros before a decimal.

decimal = Decimal(1, 3412)
print(decimal)
# Printing the Decimal as is will print off the decimal as expected.
# Result: 1.3412


decimal = Decimal(1, "0043284238472923798")
print(decimal)
# This can be expanded more to allow for more decimal places to be displayed.
# Result: 1.0043284238472923798

The Decimal class also has the following properties:

decimal.integeral
decimal.fractional
# Corresponding parts of the Decimal.

decimal.stringForm
# Will return a string version of the Decimal.

decimal.floatForm
# Will return a float version of the Decimal, note that some accuracy may be lost when doing so.

WeightedNumber

weightedNumber = WeightedNumber(100, 10)
weightedNumber = WeightedNumber(100.0, 10.0)
weightedNumber = WeightedNumber(100, 0.1)

# A WeightedNumber has two main parts, the number and the weight as a percentage (both represented as an integer or float).
# Note that when creating a WeightedNumber, the weight can either be between 0-1 or 0-100 and either will be recognized as a valid weight percentage.

weightedNumber = WeightedNumber(100, 10)
print(weightedNumber)
# Printing the WeightedNumber as is will print off the number and it's weight percentage.
# Result: 100 - 10.0%

weightedNumber = WeightedNumber(10, 0.1)
print(weightedNumber)
# As expected, both values are treated as 10%
# Result: 100 - 10.0%

The WeightedClass class also has the following properties:

weightedNumber.number
weightedNumber.weight
# Corresponding number and weight of the number in their given form.

weightedNumber.weightType
# Will return 'whole' or 'decimal' depending on the value range and type of the given weight.

weightedNumber.percentForm
# Will return the weight as a percentage.

weightedNumber.stringForm
# Will return a string version of the WeightedNumber.

weightedNumber.floatForm
# Will return a float version of the WeightedNumber (the number multiplied by the weight).

Fraction

fraction = Fraction(10, 100)
fraction = Fraction(100, 10)

# A Fraction has two main parts, the numerator and the denominator (both represented as an integer).

fraction = Fraction(10, 100)
print(fraction)
# Printing the Fraction as is will print off a simplified fraction representation of the numbers.
# Result: 1/10

The Fraction class also has the following properties:

fraction.numerator
fraction.denominator
# Corresponding numerator and denominator of the Fraction.

fraction.stringForm
# Will return a string version of the Fraction.

fraction.floatForm
# Will return a float version of the Fraction (the numerator divided by the denominator).

The Fraction class also has the following function(s):

fraction.simplify()
# Will return the Fraction simplified to have the lowest possible numerator and denominator and still be equal.

fraction = Fraction(120, 140)
print(fraction.simplify())
# Result: 6/7

Each of the classes supports the ability to have arithmetic operations be performed.

fractionA = Fraction(1, 2)
fractionB = Fraction(1, 5)


print(fractionA + fractionB)
# Result: 7/10

print(fractionA - fractionB)
# Result: 3/10

print(fractionA * fractionB)
# Result: 1/10

print(fractionA / fractionB)
# Result: 5/2

decimalA = Decimal(1, 5)
decimalB = Decimal(2, 8)


print(decimalA + decimalB)
# Result: 4.3

print(decimalA - decimalB)
# Result: -1.7

print(decimalA * decimalB)
# Result: 4.2

print(decimalA / decimalB)
# Result: 0.5357142857142857

weightedNumberA = WeightedNumber(10, 30)
weightedNumberB = WeightedNumber(10, 70)


print(weightedNumberA + weightedNumberB)
# Result: 10.0

print(weightedNumberA - weightedNumberB)
# Result: 4.0

print(weightedNumberA * weightedNumberB)
# Result: 21.0

print(weightedNumberA / weightedNumberB)
# Result: 0.42857142857142855

When performing mixed class arithmetic operations, the preceding class type will be the output type.

fraction = Fraction(1, 3)
decimal = Decimal(1, 4242)
weightedNumber = WeightedNumber(100, 30)


print(fraction + decimal)
# Result: 26363/15000
# Fraction

print(decimal + weightedNumber)
# Result: 31.4242
# Decimal

print(weightedNumber + fraction)
# Result: 30.33
# WeightedNumber

Current python int and float classes are supported in mixed class arithmetic operations.

fraction = Fraction(1, 3)
decimal = Decimal(1, 4242)
weightedNumber = WeightedNumber(100, 30)


print(2.0 - decimal)
# Result: 0.5758

print(fraction - 1)
# Result: -2/3

print(weightedNumber + 3)
# Result: 33.0
