## Actions Documentation

### Compare(Libraries.Language.Object object)

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

**Example Code**

```
Object o
Object t
integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smalle
```

#### Parameters

- Libraries.Language.Object: The object to compare to.

#### Return

integer: The Compare result, Smaller, Equal, or Larger.

### CumulativeDistribution(number x)

#### Parameters

#### Return

number

### Equals(Libraries.Language.Object object)

This action determines if two objects are equal based on their hash code values.

**Example Code**

```
use Libraries.Language.Object
use Libraries.Language.Types.Text
Object o
Text t
boolean result = o:Equals(
```

#### Parameters

- Libraries.Language.Object: The to be compared.

#### Return

boolean: True if the hash codes are equal and false if they are not equal.

### GetHashCode()

This action gets the hash code for an object.

**Example Code**

```
Object o
integer hash = o:GetHashCode
```

#### Return

integer: The integer hash code of the object.

### GetLowerBound()

#### Return

number

### GetMean()

#### Return

number

### GetSolverAbsoluteAccuracy()

#### Return

number

### GetUpperBound()

#### Return

number

### GetVariance()

#### Return

number

### InverseCumulativeDistribution(number p)

This action is an implementation of the Inverse Cumulative Distribution, which is also called the Percent Point Function. NIST describes this as NIST/SEMATECH e-Handbook of Statistical Methods, http://www.itl.nist.gov/div898/handbook/, date. https://www.itl.nist.gov/div898/handbook/eda/section3/eda362.htm

#### Parameters

#### Return

number: the result of the acti
