Returns the beta probability distribution function.
| Name | Type | Description |
| arg1 | number | The value between A and B at which to evaluate the function. |
| arg2 | number | The alpha parameter of the distribution which must be greater than 0. |
| arg3 | number | The beta parameter of the distribution which must be greater than 0. |
| arg4 | boolean | Specifies if this is the cumulative distribution function (true) or the probability density function (false). |
| arg5 | number | An optional lower bound to the interval of x (A). If omitted, it is equal to 0. |
| arg6 | number | An optional upper bound to the interval of x (B). If omitted, it is equal to 1. |
