# Math Library # Math Library
The math library is a collection of mathematical functions and constants that provide a wide range of calculations that are commonly used. 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 either integers or floats as parameters and will return the result as a float.
All functions in this library take floats or integers as parameters and will return the result as a float. The math library can usually be accessed with the `import` keyword:
The math library can be through the `import` keyword:
``` ```
import math; import math;
``` ```
## Constants ## Defined Constants
### PI: float ### PI: float
Represents the ratio of a circle's circumference to its diameter. This constant represents the ratio of a circle's circumference to its diameter. It's value is approximately `3.14159265358979323846`.
### E: float ### E: float
Represents Euler's number, the base of natural logarithms. This constant represents Euler's number, the base of natural logarithms. It's value is approximately `2.71828182845904523536`.
### EPSILON: float ### EPSILON: float
Represents the acceptable amount of approximation for floats, defaults to `0.000001`. This constant represents the acceptable amount of error when comparing floats with the functions provided by this library (see [Defined Comparison Functions](#defined-comparison-functions)). It's default value is `0.000001`.
### NAN: float ### NAN: float
Represents Not-a-Number, often returned when a calculation is impossible e.g. `sqrt(-1)` This constant represents "Not-a-Number", often returned when a calculation is impossible e.g. `sqrt(-1)`.
### INFINITY: float ### INFINITY: float
Represents the largest possible float type. This constant represents an uncountable value.
