A Rounding Function (Rnd)

You can use the rounding function (Rnd) to round the value, expression, or calculation result specified by the argument. Rounding is performed to the number of significant digits in accordance with the number of display digits setting.

Rounding for Norm1 or Norm2

The mantissa is rounded off to 10 digits.

Rounding for Fix or Sci

The value is rounded to the specified number of digits. Example: 200 ÷ 7 × 14 = 400

200/7*14E

(3 decimal places)

1Ne1(Fix)3

(Internal calculation uses 15 digits.)

200/7E

200÷7×14

400

200÷7×14

400000

200÷7

28571

*14E An s ×14

400000

Now perform the same calculation using the rounding (Rnd) function.

200/7E 200÷7

(Calculation uses rounded value.)
