NumPy - Array Data Types

What will be the output of this code?

import numpy as np
arr = np.array([1.9, 2.5, 3.1])
print(arr.astype(int))

A[1 2 3]

B[2 3 4]

C[1 3 3]

D[1.9 2.5 3.1]

Step-by-Step Solution

Solution:

Step 1: Understand float to int conversion
When converting floats to integers using astype(int), NumPy truncates the decimal part (does not round).
Step 2: Apply truncation to each element
1.9 becomes 1, 2.5 becomes 2, 3.1 becomes 3, so the output array is [1 2 3].
Final Answer:
[1 2 3] -> Option A
Quick Check:
astype(int) truncates decimals [OK]

Quick Trick: astype(int) truncates decimals, no rounding [OK]
