Percent Calculations

Inputting a value and pressing & causes the input value to become a

percent.

150 × 20% = 30

Percent Conversion

Calculation results can be converted to a percent. While a calculation

result is displayed, press !&('%). Percent display can be up to 10

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

original display format.

1 + 2 = 3 = 300%

1 ÷ 3 = 0.33 = 33.33% (Fix 2)

sd(Fix)c

= 146.6666667%

' 2 = 141.4213562%

1°2´3˝ = 103.4166667%

•

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
