If there is no exponent display, however, the mantissa can be up to 10 digits. •When a complex number has more than 16 digits, the real number part and imaginary number part are displayed on separate lines. •When either the real number part or imaginary number part equals zero, that part is not displayed. •20 bytes of memory are used whenever you assign a complex number to a value memory (page 40). •The following functions can be used with complex numbers. r, x2, x I Int, Frac, Rnd, Intg, Fix, Sci, ENG, ENG ab/c, d/c -93-
