Funx.Math
Mix.install([
{:funx, "0.8.8"}
])Provides mathematical operations using Monoids.
This module uses the Sum and Product monoids to perform operations
such as addition and multiplication over values or lists of values.
sum/2
Sums two numbers using the Sum monoid.
Examples
Funx.Math.sum(1, 2)sum/1
Sums a list of numbers using the Sum monoid.
Examples
Funx.Math.sum([1, 2, 3])Funx.Math.sum([])product/2
Multiplies two numbers using the Product monoid.
Examples
Funx.Math.product(3, 4)product/1
Multiplies a list of numbers using the Product monoid.
Examples
Funx.Math.product([2, 3, 4])Funx.Math.product([])max/2
Returns the maximum of two numbers using the Max monoid.
Examples
Funx.Math.max(3, 7)Funx.Math.max(-1, -5)max/1
Finds the maximum value in a list using the Max monoid.
Returns Float.min_finite() if the list is empty.
Examples
Funx.Math.max([3, 7, 2])Funx.Math.max([])min/2
Returns the minimum of two numbers using the Min monoid.
Examples
Funx.Math.min(3, 7)Funx.Math.min(-1, -5)min/1
Finds the minimum value in a list using the Min monoid.
Returns Float.max_finite() if the list is empty.
Examples
Funx.Math.min([3, 7, 2])Funx.Math.min([])mean/1
Computes the arithmetic mean of a list of numbers.
Returns Nothing if the list is empty.
Examples
Funx.Math.mean([1, 2, 3, 4])Funx.Math.mean([])range/1
Computes the range (difference between max and min) of a list.
Returns nothing() if the list is empty.
Examples
Funx.Math.range([3, 7, 2])Funx.Math.range([])square/1
Computes the square of a number.
Examples
Funx.Math.square(3)Funx.Math.square(-4)sum_of_squares/1
Computes the sum of squares of a list of numbers.
Returns 0 if the list is empty.
Examples
Funx.Math.sum_of_squares([1, 2, 3])Funx.Math.sum_of_squares([-2, 5])Funx.Math.sum_of_squares([])deviation/1
Computes the deviations from the mean for a list of numbers.
Returns Nothing if the list is empty.
Examples
Funx.Math.deviation([1, 2, 3, 4])Funx.Math.deviation([5, 5, 5])Funx.Math.deviation([])variance/1
Computes the variance of a list of numbers.
Returns Nothing if the list is empty.
Examples
Funx.Math.variance([1, 2, 3, 4])Funx.Math.variance([5, 5, 5])Funx.Math.variance([])std_dev/1
Computes the standard deviation of a list of numbers.
Returns Nothing if the list is empty.
Examples
Funx.Math.std_dev([1, 2, 3, 4])Funx.Math.std_dev([5, 5, 5])Funx.Math.std_dev([])
