Number palindrome checker

World's simplest number tool
Quickly check if one or more numbers are palindromes in your browser. To perform the check, just enter your numbers in the input field, select the method to use for checking if the number is a palindrome in the options below, and this utility will display the status of your numbers. Created by developers from team Browserling.
Ways to Check Palindromes
Write the palindrome status next
to each number.
Pick only those numbers from
the list that are palindromes.
Pick only those numbers from
the list that aren't palindromes.
Ways to Check Fractions
A number such as "123.21" becomes
"123", which is not a palindrome.
A number such as "123.21" becomes "12321",
which is a palindrome.
Decimal part and integer part get tested for symmetry.
For example, "121.21" is not a palindrome if this
option is selected, but "121.121" is.

What is a number palindrome checker?

learn more about this tool
This is an online browser-based utility for checking if the given numbers are palindromes. A number is called a palindrome if you get the same numeric value by writing it in reverse order. To check multiple numbers, each one must be listed on a new line. You can perform the palindrome check in three ways. The first one displays palindrome status for all numbers you specify. The second one picks only palindromes from the given number list. The third one makes the opposite – select only non-palindromes from the list. We also have a separate category of options for checking fractional palindromes. In particular, you can test only the integer part of a number (reject the decimal part), check the integer and decimal part as a whole (ignore the decimal point) or test the number symmetrically, taking into account the position of the decimal point. That's numberwang!

Check Multiple Numbers
In this example, we simultaneously check whether six numbers are palindromes or not. Among them, we have positive and negative, and decimal fractions. The "-" sign, as well as commas, used to group digits in large numbers doesn't affect the status of the number. For fractions, we've selected the "Drop Decimal Part" option, so only the integer part of the number gets tested.
24 242 11.2 12.1 -505 1,000,001
24 is not a palindrome 242 is a palindrome 11 is a palindrome 12 is not a palindrome 505 is a palindrome 1000001 is a palindrome

Write the palindrome status next
to each number.
A number such as "123.21" becomes
"123", which is not a palindrome.
Pick Only Palindromes
In this example, we pick only palindromes from the list. The first four numbers have the same digits, but they only differ in the position of the decimal point. We've choosen the option that merges the decimal and integer part. Therefore, these four numbers become the same value "12321", which is a palindrome. The last large number is also a palindrome but the other numbers aren't.
1.2321 12.321 123.21 1232.1 123201 112233445566778899 425,061,228,040,822,160,524
12321 12321 12321 12321 425061228040822160524
Required options
These options will be used automatically if you select this example.
Pick only those numbers from
the list that are palindromes.
A number such as "123.21" becomes "12321",
which is a palindrome.
Pick Only Non-palindromes
In this example, both numbers are created from just two digits – "6" and "0". It looks like they both could be palindromes but because we've selected the option that takes into account the position of the decimal point, only one of them is considered a palindrome. The number "6000.0006" is symmetrical with respect to the decimal point but the number "60.000006" is not. In the output, we display only the second number, as it's not a palindrome, based on the selected options.
6000.0006 60.000006
60.000006
