Percent Calculations

Inputting a value and pressing 1((%) causes the input value to become
a percent.
150 × 20% = 30
Calculate what percentage of 880 is 660. (75%)
Increase 2500 by 15%. (2875)
Discount 3500 by 25%. (2625)
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
is the input format for a sexagesimal value: {degrees} $ {minutes} $
{seconds} $.
Note: You must always input something for the degrees and minutes, even
if they are zero.
2°20´30˝ + 39´30˝ = 3°00´00˝
Convert 2°15´18˝ to its decimal equivalent.
Multi-Statements
You can use the colon character (:) to connect two or more expressions and
execute them in sequence from left to right when you press =.

Using Engineering Notation

A simple key operation transforms a displayed value to engineering
notation.
Transform the value 1234 to engineering notation, shifting the
decimal point to the right.
