Solution in Python:


import math

def check_for_palindrome_number(n):

    assert n >= 0

    n_digits = int(math.floor(math.log10(n)))

    upper_mult = 10 ** n_digits
    lower_mult = 10

    while lower_mult <= upper_mult:
        lower = (n % lower_mult) // (lower_mult // 10)
        upper = (n // upper_mult) % 10

        if lower != upper:
            return False

        lower_mult *= 10
        upper_mult //=10

    return True
