Series - Float

SeriesF32 is a Series where the type of the vector is FloatsVector and the Series name is a string.

The following scripts assume that you have imported the SeriesF32 object from the package and set up the threads as explained in getting started.

note

Use .display on SeriesF32 to view the Series.

Use .data on SeriesF32 to view FloatsVector of the Series.

Constructors Methods

These methods are used to create new SeriesF32.

// Create an SeriesF32 from a given JavaScript array    let s = new SeriesF32("Grades", [9.5, 9.0, 7.8, 8.5]);    console.log(s.display);     /*    +--------+    | Grades |    +--------+    | 9.5    |    +--------+    | 9      |    +--------+    | 7.8    |    +--------+    | 8.5    |    +--------+    */

Interop Methods

Some handy methods to work with the Series.

// Return Json representation of Series    let s = new SeriesF32("Grades", [9.5, 9.0, 7.8, 8.5]);    console.log(s.toJson());    // {name: "Grades", data: Array(4)}
// Return String Series Representation    console.log(s.display)    /*    +--------+    | Grades |    +--------+    | 9.5    |    +--------+    | 9      |    +--------+    | 7.8    |    +--------+    | 8.5    |    +--------+    */
// Return FloatsVector of Series    console.log(s.data())    // [9.5, 9.0, 7.8, 8.5]

Utility Methods

Basic getters and setters.

// Create an SeriesF32 from a given JavaScript array    let s = new SeriesF32("Grades", [9.5, 9.0, 7.8, 8.5]);
// Get the length of the array    console.log(s.len());     // 4
// Set the given value at the specified index    s.set(1, 10);     // [9.5, 10, 7.8, 8.5]    console.log(s.display)     // Use to view Series in console
// Get the value at the specified index    console.log(s.get(3));     // 8.5
// Swap the values at the specified indices    s.swap(0, 1);     // [10, 9.5, 7.8, 8.5]    console.log(s.display);     // Use to view Series in console

More complex methods used to manipulate the SeriesF32. Each of these methods has two versions. The "pure" version returns the result of performing the operation while the "impure" version actually changes the FloatsVector.

Pure	Impure
reverse	reversed
append	appended
extend	extended
insert	inserted
splice	spliced

// Create an SeriesF32 from a given JavaScript array    let s = new SeriesF32("Grades", [9.5, 9.0, 7.8, 8.5]);
// Reverse the Series Data    s.reverse();     // [8.5, 7.8, 9.0, 9.5] (without return)    console.log(s.reversed().data);     // [8.5, 7.8, 9.0, 9.5]
// Append an element to the Series    s.append(10);     // [8.5, 7.8, 9.0, 9.5, 10] (without return)    console.log(s.appended(33).data)     // [8.5, 7.8, 9.0, 9.5, 10] 
// Extend the FloatsVector with another    s.extend([7.5, 8.5]);     // [8.5, 7.8, 9.0, 9.5, 10, 7.5, 8.5]  (without return)       console.log(s.extended([7.5, 8.5]).data);     // [8.5, 7.8, 9.0, 9.5, 10, 7.5, 8.5]
// Insert the given element at the specified index    s.insert(2, 6);     // [8.5, 7.8, 6, 9.0, 9.5, 10, 7.5, 8.5] (without return)    console.log(s.inserted(2, 6).data);    // [8.5, 7.8, 6.0, 9.0, 9.5, 10, 7.5, 8.5]
// Removes an element from the specified index    console.log(s.splice(0));     // 8.5
// Remove the value at the specified index and return the array    console.log(s.spliced(6)[0].data);     // [7.8, 6.0, 9.0, 9.5, 10, 7.5]

Math Methods

Methods to perform simple mathematical operations on the Series.

// Create an SeriesF32 from a given JavaScript array    let s = new SeriesF32("Grades", [9.5, 9.0, 7.8, 8.5]);
// SeriesF32 max    console.log(s.max());    // 9.5
// SeriesF32 min    console.log(s.min());    // 7.8
// SeriesF32 sum    console.log(s.sum());    // 34.8
// SeriesF32 product    console.log(s.product());    // 5668.65
// SeriesF32 mean    console.log(s.mean());    // 8.7
// SeriesF32 median    console.log(s.median());    // 8.75
// SeriesF32 standard deviation  params (degree_of_freedom)    console.log(s.std_dev(1));    // 0.7257180352359078
// SeriesF32 variance params (degree_of_freedom)    console.log(s.variance(1));    // 0.5266666666666663
