Converting a float array into an integer array is a common task in programming. This operation can be useful when working with datasets that contain numerical values that need to be represented as integers, such as pixel intensities in images or categorical variables in machine learning models. There are different ways to convert a float (32 bits) array into an integer (32 bits) array using NumPy. Some possible methods are:

#### 1. By "astype()" method:

`astype()`

is a method in NumPy that is used to cast an array to a specified data type. It takes a single argument, which is the data type to which the array should be cast. The `astype()`

method returns a new array with the specified data type.

The `astype()`

method can be used to convert the data type of a NumPy array. To convert a float (32 bits) array to an integer (32 bits) array, we can use astype(‘int32’).

#### 2. By "view()" method:

In NumPy, the `view()`

method is used to create a new view of an existing array with the same data. The view shares the same memory as the original array, but it can have a different shape or data type. creating a view of an array is a very fast operation and does not require copying the data, making it useful for working with large datasets.

The `view()`

method can be used to change the interpretation of the data in a NumPy array. To convert a float (32 bits) array to an integer (32 bits) array, we can use view(np.int32).

#### 3. By "array()" method with "dtype" :

In NumPy, the `array()`

method is used to create a new array with the specified data type. The `dtype`

parameter is used to specify the data type of the new array. The `array()`

method can be used with many different data types, including integers, floats, booleans, and complex numbers.

The `array()`

method can be used to create a new NumPy array with a specified data type. To convert a float (32 bits) array to an integer (32 bits) array in place, we can use the array() method with dtype=‘int32’.
