[John Taylor]

New submission from John Taylor:

The print statement does not display accurate results.

code:
    print("%35d" % (1e21))
    print("%35d" % (1e22))
    print("%35d" % (1e23))
    print("%35d" % (1e24))
    print("%35d" % (1e25))
    print("%35d" % (1e26))
    print("%35d" % (1e27))
    print("%35d" % (1e28))
    print("%35d" % (1e29))
    print("%35d" % (1e30))
    print("%35d" % (1e31))

result:
             1000000000000000000000
            10000000000000000000000
