To round all of the values in the data array, you can pass data as the argument to the np.round() function. You set the desired number of decimal places with the decimals keyword argument. The NumPy function uses the round half to even strategy, just like Python’s built-in round()...

NumPy can support many different data types, but its primary focus is on numerical data types, such as floating-point numbers, and non-numerical data types, such as text strings, which might see little benefit from NumPy array storage compared to other array storage mechanisms such as Python ...

To replace values in a NumPy array by index in Python, use simple indexing for single values (e.g., array[0] = new_value), slicing for multiple values (array[start:end] = new_values_array), boolean indexing for condition-based replacement (array[array > threshold] = new_value), and...
