Package Exports

choose-typed-array

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (choose-typed-array) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

choose-typed-array

Chooses the Best Typed Array to Hold an Array of Numbers. Supports Big Integers!

install

npm install choose-typed-array

usage

The function takes in 4 variables:

all_numbers_are_integers: whether all the numbers in the array are integers
min: the lowest number in the array
max: the highest number in the array
max_significant_digits: the largest instance of significant digits found in the array (you don't need to specify this if all the numbers are integers)

const chooseTypedArray = require("choose-typed-array");

// for an array of 1s and 0s like [0, 1, 0, 1, 1, 1, 0]
const TypedArray = chooseTypedArray({
    min: 0,
    max: 1,
    all_numbers_are_integers: true
});
// TypedArray is Uint8Array

// for an array of pixel values like [0, 255, 128, 123, 32, 94]
const TypedArray = chooseTypedArray({
    min: 0,
    max: 255,
    all_numbers_are_integers: true
});
// TypedArray is Uint8Array

// for an array of larger values like [-1273, 1238, -1243, 322, -945]
const TypedArray = chooseTypedArray({
    min: -1273,
    max: 1238,
    all_numbers_are_integers: true
});
// TypedArray is Uint16Array

// for an array of random numbers [0.6133360105966696, 0.9000317453847548, 0.20715335681564762, 0.4200819399746838, ...]
const TypedArray = chooseTypedArray({
    min: -1273,
    max: 1238,
    all_numbers_are_integers: true
    max_significant_digits: 16
});
// TypedArray is Float64Array
