The F

with the display format setting.

At the same time, the number of digits below the decimal point of the above modes follows the

display format assigned by the 2ndF and F

↔ E keys.

Further, in the same manner as the F

with the display format setting.

When the number of digits is specified, the last digit displayed is a rounded number, and when

there is no specification of the number of digits, the last digit displayed is a cut number.
