# Python | Filter out integers from float numpy array

• Last Updated : 20 Jul, 2021

Given a numpy array, the task is to filter out integers from an array containing float and integers. Let’s see few methods to solve a given task.
Method #1 : Using astype(int)

## Python3

 `# Python code to demonstrate``# filtering integers from numpy array``# containing integers and float` `import` `numpy as np` `# initialising array``ini_array ``=` `np.array([``1.0``, ``1.2``, ``2.2``, ``2.0``, ``3.0``, ``2.0``])` `# printing initial array``print` `(``"initial array : "``, ``str``(ini_array))` `# filtering integers``result ``=` `ini_array[ini_array !``=` `ini_array.astype(``int``)]` `# printing resultant``print` `(``"final array"``, result)`

Output:

```initial array :  [ 1.   1.2  2.2  2.   3.   2. ]
final array [ 1.2  2.2]```

Method #2: Using np.equal() and np.mod()

## Python3

 `# Python code to demonstrate``# filtering integers from numpy array``# containing integers and float` `import` `numpy as np` `# initialising array``ini_array ``=` `np.array([``1.0``, ``1.2``, ``2.2``, ``2.0``, ``3.0``, ``2.0``])` `# printing initial array``print` `(``"initial array : "``, ``str``(ini_array))` `# filtering integers``result ``=` `ini_array[~np.equal(np.mod(ini_array, ``1``), ``0``)]` `# printing resultant``print` `(``"final array : "``, ``str``(result))`

Output:

```initial array :  [ 1.   1.2  2.2  2.   3.   2. ]
final array :  [ 1.2  2.2]```

Method #3: Using np.isclose()

## Python3

 `# Python code to demonstrate``# filtering integers from numpy array``# containing integers and float` `import` `numpy as np` `# initialising array``ini_array ``=` `np.array([``1.0``, ``1.2``, ``2.2``, ``2.0``, ``3.0``, ``2.0``])` `# printing initial array``print` `(``"initial array : "``, ``str``(ini_array))` `# filtering integers``mask ``=` `np.isclose(ini_array, ini_array.astype(``int``))``result ``=` `ini_array[~mask]` `# printing resultant``print` `(``"final array : "``, ``str``(result))`

Output:

```initial array :  [ 1.   1.2  2.2  2.   3.   2. ]
final array :  [ 1.2  2.2]```
