# Math Library The math library is a collection of mathematical functions and constants that provide a wide range of calculations that are commonly used. All functions in this library take floats or integers as parameters and will return the result as a float. The math library can be through the `import` keyword: ``` import math; ``` ## Constants ### PI: float Represents the ratio of a circle's circumference to its diameter. ### E: float Represents Euler's number, the base of natural logarithms. ### EPSILON: float Represents the acceptable amount of approximation for floats, defaults to `0.000001`. ### NAN: float Represents Not-a-Number, often returned when a calculation is impossible e.g. `sqrt(-1)` ### INFINITY: float Represents the largest possible float type. ## Power ### pow(x, y): float Returns `x` to the power of `y`. ### sqrt(x): float Returns the square root of `x`. ### qbrt(x): float Returns the cube root of `x`. ### hypot(x, y): float Returns the length of the hypotenuse assuming `x` and `y` are the legs in a right-angle triangle. ## Trigonometric ## toRadians(d): float Converts `d` into radians. ## toDegrees(r): float Converts `r` into degrees. ## sin(x): float Returns the sine of `x`. ## cos(x): float Returns the cosine of `x`. ## tan(x): float Returns the tangent of `x`. ## asin(x): float Returns the arc sine of `x`. ## acos(x): float Returns the arc cosine of `x`. ## atan(x): float Returns the arc tangent of `x`. ## Hyperbolic ## sinh(x): float Returns the hyperbolic sine of `x` ## cosh(x): float Returns the hyperbolic cosine of `x` ## tanh(x): float Returns the hyperbolic tangent of `x` ## asinh(x): float Returns the inverse hyperbolic sine of `x` ## acosh(x): float Returns the inverse cosine sine of `x` ## atanh(x): float Returns the inverse tangent sine of `x` ## Comparison ### checkIsNaN(x): bool Returns true if `x` is NaN and false otherwise. ### chechIsFinite(x): bool Returns true if `x` is finite or in otherwords it is not Infinite or NaN. ### chechIsInfinite(x): bool Returns true if `x` is Infinite and false otherwise. ### epsilionCompare(x, y): bool Returns true if `x` or `y` are within epsilon of each other, otherwise it returns false. This is very useful for compairing floating point values.
