# Htam
A fork of the Math package.
The Math module adds many useful functions that extend Elixir's standard library.
- General Functions
- `a <~> b` Comparison of floats, to check if they are _nearly_ equal.
- `Math.pow(x, n)` Arithmetic exponentiation. Works both with integer powers and floats.
- `Math.sqrt(x)` The square root of *x*.
- `Math.nth_root(x, n)` The n-th root of *x*.
- `Math.isqrt(x)` The integer square root of *x*.
- `Math.gcd(a, b)` The greatest common divisor of *a* and *b*.
- `Math.lcm(a, b)` The least common multiple of *a* and *b*.
- `Math.factorial(n)` The *n*-th factorial number.
- `Math.k_permutations(n, k)` The number of distinct ways to create groups of size *k* from *n* distinct elements.
- `Math.k_combinations(n, k)` The number of distinct ways to create groups of size *k* from *n* distinct elements where order does not matter.
- Logarithms
- `Math.exp(x)` Calculates ℯ to the xth power.
- `Math.log(x)` Calculates the natural logarithm (base `ℯ`) of *x*.
- `Math.log(x, b)` Calculates the base-*b* logarithm of *x*
- `Math.log2(x)` Calculates the binary logarithm (base `2`) of *x*.
- `Math.log10(x)` Calculates the common logarithm (base `10`) of *x*.
- `Math.e` Returns a floating-point approximation of the number ℯ.
- Trigonometry
- `Math.pi` Returns a floating-point approximation of the number *π*.
- `Math.deg2rad(x)` converts from degrees to radians.
- `Math.rad2deg(x)` converts from radians to degrees.
- `Math.sin(x)` The sine of *x*.
- `Math.cos(x)` The cosine of *x*.
- `Math.tan(x)` The tangent of *x*.
- `Math.asin(x)` The inverse sine of *x*.
- `Math.acos(x)` The inverse cosine of *x*.
- `Math.atan(x)` The inverse tangent of *x*.
- `Math.atan2(x, y)` The inverse tangent of *x* and *y*. This variant returns the inverse tangent in the correct quadrant, as the signs of both *x* and *y* are known.
- `Math.sinh(x)` The hyperbolic sine of *x*.
- `Math.cosh(x)` The hyperbolic cosine of *x*.
- `Math.tanh(x)` The hyperbolic tangent of *x*.
- `Math.asinh(x)` The inverse hyperbolic sine of *x*.
- `Math.acosh(x)` The inverse hyperbolic cosine of *x*.
- `Math.atanh(x)` The inverse hyperbolic tangent of *x*.
- Working with Collections
- `Math.Enum.product(collection)` The result of multiplying all elements in the passed collection.
- `Math.Enum.mean(collection)` the mean of the numbers in the collection.
- `Math.Enum.median(collection)` the median of the numbers in the collection.
## Installation
The package can be installed by adding `htam` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:htam, "~> 0.1.0"}
]
end
```
Require or import the Math library anywhere in your code you'd like:
require Math
or
import Math
(Importing allows usage of the `<~>` operator)
```
