Integers are printed in the radix specified by the current output base in positional notation, most significant digit first. If appropriate, a radix specifier can be printed; see *print-radix*. If an integer is negative, a minus sign is printed and then the absolute value of the integer is printed. The integer zero is represented by the single digit 0 and never has a sign. A decimal point might be printed, depending on the value of *print-radix*.
