Reversing an Integer's Digits

[Didier Lachieze]

Thanks for that. The addition to reverse a number is a nice trick if you have an easy way to get access to the individual digits.

Otherwise on the Prime you can also use this one liner that you can define as a user function to reverse the number N:

EXPR(CHAR(REVERSE(ASC(STRING(N)))))

It works with integers and also with positive decimal numbers, for example for 67.28 it returns 82.76

To reverse both positive and negative numbers you need:

SIGN(N)*EXPR(CHAR(REVERSE(ASC(STRING(ABS(N))))))
