- a_list = [1.234, 2.345, 3.45, 1.45]
- np_array = np. array(a_list)
- np_round_to_tenths = np. around(np_array, 1)
- round_to_tenths = list(np_round_to_tenths)
- print(round_to_tenths)

### How do I round off numbers in Numpy?

- Step 5 – Lets look at our dataset now.

**How do I round a Numpy float?**

To round the elements of a float array in python, a solution is to use the numpy function around, example: >>> import numpy as np >>> A = np. array((0.4, 1.6, 2.1, -0.7, 0.9)) >>> np. around(A) array([ 0., 2., 2., -1., 1.])

#### How do you round to 2 decimal places in python?

**Why does NumPy round to the nearest even value?**

For values exactly halfway between rounded decimal values, NumPy rounds to the nearest even value. Thus 1.5 and 2.5 round to 2.0, -0.5 and 0.5 round to 0.0, etc. Results may also be surprising due to the inexact representation of decimal fractions in the IEEE floating point standard [R9] and errors introduced when scaling by powers of ten.

### What’s the default value for round in Python?

Default = 0. In case of -ve decimal, it specifies the n0. of positions to the left of the decimal point. An array with all array elements being rounded off, having same type as input.

### How to round a floating point number in Python?

When you let the Python environment display a floating-point number, it uses the __repr__ conversion function which shows enough digits to unambiguously identify the number. If you use the __str__ conversion instead, it should round the number to a reasonable number of digits.
