= y. The Operand and
Result words have the format:
x = exponent of 10 (maximum value = 5.999 999)
y = resultant number (maximum of 6 digits)

Enter values for the operand. You can enter these values from the
keyboard of your 1770-T3 terminal or through ladder diagram functions.
Entry of an operand (exponent of 10) of 000 002 . 386 000 yields an
exponential value of 000 243 . 221 000. Figure 14.18 shows how it is
stored in the data table.
