How to Declare a Float Array in TypeScript - Step by Step Examples



How to Declare a Float Array in TypeScript ?

Answer

To declare a float array in TypeScript, you can use array literal notation or the Array constructor.



✐ Examples

1 Declare and Initialize a Float Array

In this example,

  1. We declare a float array named floatArray with predefined values using array literal notation.
  2. We log the array to the console to demonstrate the initialization.

TypeScript Program

let floatArray: number[] = [1.2, 3.4, 5.6];
console.log('Float Array:', floatArray);

Output

Float Array: [ 1.2, 3.4, 5.6 ]

2 Declare an Empty Float Array

In this example,

  1. We declare an empty float array named emptyFloatArray using the Array constructor without any elements.
  2. We log the array to the console to demonstrate the declaration.

TypeScript Program

let emptyFloatArray: number[] = new Array();
console.log('Empty Float Array:', emptyFloatArray);

Output

Empty Float Array: []
