Numbers filter tool
What is a numbers filter?

This is an online browser-based utility for selecting numbers that match certain criteria. In particular, you can quickly filter all integers, decimals, even numbers, and odd numbers from a specific range. If the field "Lower Bound" is empty, then the numbers are not bound below, and if the field "Upper Bound" is empty, then the numbers are not bound above. You can also filter all values that are multiples of a certain number or divisors of a certain number. If your numbers are separated in a non-standard way, then you can adjust the delimiter that separates them in the input list. You can also do the same for the filtered list. In addition, you can sort the filtered numbers from the smallest to the largest. That's numberwang!

Filter All Positive Fraction

In this example, we filter all numbers that have a fractional part. We set the lower bound equal to 0 and leave the upper bound field empty. This means that the filtered decimal numbers will be only positive.

-20
970
7.9
2460
8.2
450
-0.6
0.1
9.5
-505
2.4
25

7.9
8.2
0.1
9.5
2.4

**Required options**

Lower Bound.

Upper Bound.

Pick all decimal numbers from the list.

Pick all numbers that are
multiples of n.

Pick all numbers that are
divisors of m.

Input number delimiter.
(By default a new line.)

Filtered number delimiter.
(By default a new line.)

Sort filtered numbers from
the smaller to largest.

Filter Multiples of 3

This example filters a list of 20 integers. The filtering criteria is set to select only those numbers that are multiples of 3 (that is, numbers that are divisible by 3 without a remainder). We separate the input sequence of numbers by a comma character and filtered numbers by a semicolon character. We also sort the selected numbers in ascending order.

1, 24, 91, 940, 45, 32, 120, 410, 16, 88, 5, 252, 5040, 158, 18, 121, 6, 160, 16, 202

6; 18; 24; 45; 120; 252; 5040

**Required options**

Lower Bound.

Upper Bound.

Pick all whole numbers from the list.

Pick all numbers that are
multiples of n.

Enter the multiple number (n).

Pick all numbers that are
divisors of m.

Input number delimiter.
(By default a new line.)

Filtered number delimiter.
(By default a new line.)

Sort filtered numbers from
the smaller to largest.

Filter Divisors of One Million

In this example, we filter only those values that are divisors of one million. In addition, we make the filter to select only even numbers. We sort the output numbers in increasing order and separate them with the comma symbol.

-25 50 -73 -8 3 92 -5 -80 -54 55 -71 89 58 17 19 83 -42 -22 29 -10 -56 -64 -34 -40 -27 31 21 55 -30 -92 -35 -58 -77 6 -69 35 -78 -99 -58 -100 79 -68 33 -75 75 -73 -93 -62 9 -66 -65 80 -85 -22 -59 67 -75 43 11 60 93 -49 -24 96 62 67 -40 32 20 -77 30 0 -35 36 -83 40 51 40 19 -31 45 52 24 -74 60 -93 12 75 -69 71 38 -90 16 83 -61 -90 -67 26 81 -32

-100, -80, -64, -40, -40, -32, -10, -8, 16, 20, 32, 40, 40, 50, 80

**Required options**

Lower Bound.

Upper Bound.

Pick all even numbers from the list.

Pick all numbers that are
multiples of n.

Pick all numbers that are
divisors of m.

Enter the number divisor (m).

Input number delimiter.
(By default a new line.)

Filtered number delimiter.
(By default a new line.)

Sort filtered numbers from
the smaller to largest.
