digits long. Pressing !&('%) again returns the calculation result to its

• When the number of display digits is specified by Fix, the value is converted
to a percent and then adjusted to the specified number of digits. The number
of display digits setting is not applied to the value stored in Ans memory.
• When MathO is selected as the display format and the calculation result is
a fraction, root ('), or pi (π), the result is converted to a decimal fraction
and then to a percent. Pressing !&('%) again displays the decimal
fraction value.
• When the calculation result is a sexagesimal value (degrees, minutes,
seconds), it is converted to a decimal value and then to a percent.
• Percent conversion cannot be performed on the result of a remainder
calculation (÷R).
Degree, Minute, Second (Sexagesimal) Calculations
Performing an addition or subtraction operation between sexagesimal values,
or a multiplication or division operation between a sexagesimal value and a
decimal value will cause the result to be displayed as a sexagesimal value.
You also can convert between sexagesimal and decimal. The following
