Palindrome Types
Use fold symmetry with respect to the last digit. For example, "123" becomes "12321".
Use mirror reflection of the number. For example, "123" becomes "123321".
Fraction Options
Create palindromes only from the integer part. For example, the number "123.45" becomes "12321" (or "123321").
Create palindromes from the integer and decimal parts. For example, the number "123.45" becomes "123.454321" (or "123.4554321").
Number palindrome creator tool What is a number palindrome creator?
This is an online browser-based utility for creating palindromes from the given numbers. A palindrome number is a number that has the same value independent of the reading direction. For example, 34943 is a palindrome number because it has the same value from the left side and the right side. We offer two modes for creating palindromes. The first one makes a symmetric number with respect to its last digit. For example, 246 becomes 24642. The second makes a complete mirror reflection and repeats the last digit twice. For example, 135 becomes 135531. We also have a feature for creating palindromes from fractional numbers. For example, a decimal number 55.987 becomes 55.9878955. That's numberwang!

Centered Palindromes
In this example, we create palindromes from six numbers. To do it, we use fold symmetry with respect to the last digit. What that means is that the number 24 (first number in the example) gets unfolded along the last digit and gets converted into 242, which is a palindrome. The digit 4 itself isn't duplicated. If the number is fractional, then we take only the integer part. Take a look at the last number 245.68. It gets palindromized into 24542 (digits "6" and "8" are deleted because they belong to the decimal fraction part).
24 10000 -1489 5,125 245.68
242 100000001 -1489841 5125215 24542

Mirrored Palindromes
In this example, we create mirror palindromes from three numbers. We place a mirror at the end of the number and write everything that we see one more time. As a result, all the digits get duplicated from right to left. The first number, 24, in the example gets converted into 2442. We also mirror the decimal part here. Thus, the number 975.420 (second number in the example) becomes 975.420024579.
24 975.420 10,202,303,404
2442 975.420024579 1020230340440430320201
