Explanation: In the above exercise - nums = np.array([1.2e-7, 1.5e-6, 1.7e-5]) creates a NumPy array with three small floating-point numbers in scientific notation. np.set_printoptions(suppress=True, precision=10) sets the global print options for NumPy. The suppress=True option disables...

print("Array Size:", arr.size) print("Shape:", arr.shape) # Output: Array Size: 8 Shape: (2, 4) 6. NumPy Array Data Types NumPy supports a much greater variety of numerical types than Python does. The following table shows different scalar data types defined in NumPy tutorial. ...
For e, E and f specifiers, the number of digits to print after the decimal point. For g and G, the maximum number of significant digits. For s, the maximum number of characters. specifiers: c : character d or i : signed decimal integer e or E : scientific notation with e or E. ...
You probably noticed that in examples 1 and 2, the numbers were in scientific notation. I’m not sure that that’ necessary, since the numbers in our Numpy array are integers. So, let’s save the data in integer format, in the output array. ...

In the following example, you’ll create the my_array array that you have already played around with above: import numpy as np # Make the array `my_array` my_array = np.array([[1,2,3,4], [5,6,7,8]], dtype=np.int64) # Print `my_array` print(my_array) Powered By If you...
