|
Floor |
Returns the floor of a number. |
Calculates the hypotenuse. |
|
Max |
Returns the maximum number from an array of numbers. |
Returns the mean, or average, value from an array of numbers. |
|
Return the median value from an array of numbers. |
|
Min |
Returns the minimum number from an array of numbers. |
Returns a point at an angle and distance from the point. |
|
Solves a quadratic equation. |
|
Sum |
Returns the sum number from an array of numbers. |
Note, the following non-intrinsic math functions can be derived from the intrinsic math functions:
