PackedFloat64Array

A packed Array of 64-bit floating-point values.

Description

An Array specifically designed to hold 64-bit floating-point values. Packs data tightly, so it saves memory for large array sizes.

If you only need to pack 32-bit floats tightly, see PackedFloat32Array for a more memory-friendly alternative.

Constructor Descriptions

Constructs an empty PackedFloat64Array.


Constructs a PackedFloat64Array as a copy of the given PackedFloat64Array.


Constructs a new PackedFloat64Array. Optionally, you can pass in a generic Array that will be converted.

Method Descriptions

Appends an element at the end of the array (alias of push_back).


Appends a PackedFloat64Array at the end of this array.


Finds the index of an existing value (or the insertion index that maintains sorting order, if the value is not yet present in the array) using binary search. Optionally, a before specifier can be passed. If false, the returned index comes after all existing entries of the value in the array.

Note: Calling bsearch on an unsorted array results in unexpected behavior.


Creates a copy of the array, and returns it.


  • void fill ( float value )

Assigns the given value to all elements in the array. This can typically be used together with resize to create an array with a given size and initialized elements.


Returns true if the array contains value.


Inserts a new element at a given position in the array. The position must be valid, or at the end of the array (idx == size()).


  • bool is_empty ( ) const

Returns true if the array is empty.


Appends an element at the end of the array.


  • void remove ( int index )

Removes an element from the array by index.


Sets the size of the array. If the array is grown, reserves elements at the end of the array. If the array is shrunk, truncates the array to the new size.


  • void reverse ( )

Reverses the order of the elements in the array.


Changes the float at the given index.


  • int size ( ) const

Returns the size of the array.


  • void sort ( )

Sorts the elements of the array in ascending order.



Returns a copy of the data converted to a PackedByteArray, where each element have been encoded as 8 bytes.

The size of the new array will be float64_array.size() * 8.

Operator Descriptions

  • bool operator != ( )




  • bool operator == ( )
