# NumPy: Calculate round, floor, ceiling, truncated and round of the input, element-wise of a given array

## NumPy Mathematics: Exercise-26 with Solution

Write a NumPy program to calculate round, floor, ceiling, truncated and round (to the given number of decimals) of the input, element-wise of a given array.

Sample Solution:-

Python Code:

``````import numpy as np
x = np.array([3.1, 3.5, 4.5, 2.9, -3.1, -3.5, -5.9])
print("Original array: ")
print(x)
r1 = np.around(x)
r2 = np.floor(x)
r3 = np.ceil(x)
r4 = np.trunc(x)
r5 = [round(elem) for elem in x]

print("\naround:   ", r1)
print("floor:    ",r2)
print("ceil:     ",r3)
print("trunc:    ",r4)
print("round:    ",r5)
```
```

Sample Output:

```Original array:
[ 3.1  3.5  4.5  2.9 -3.1 -3.5 -5.9]

around:    [ 3.  4.  4.  3. -3. -4. -6.]
floor:     [ 3.  3.  4.  2. -4. -4. -6.]
ceil:      [ 4.  4.  5.  3. -3. -3. -5.]
trunc:     [ 3.  3.  4.  2. -3. -3. -5.]
round:     [3.0, 4.0, 4.0, 3.0, -3.0, -4.0, -6.0]
```

## Python: Tips of the Day

Getting rid of unwanted characters:

You can get rid of whitespaces or any specific character using strip methods in Python. You can use either plain strip for both sides, lstrip for the left side and rstrip for the right side only.

```str="+++Welcome python+++"
str.strip()

print(str)```

Output:

`+++Welcome python+++`
