Setting Options
Angle Measure Degrees—360 degrees in a circle.
Radians—2π radians in a circle.
The angle mode you set is the angle setting used in both Home view and the current
app. This is to ensure that trigonometric calculations done in the current app and
Home view give the same result.
Number Format The number format you set is the format used in all Home view calculations.
●
Standard—Full-precision display.
●
Fixed—Displays results rounded to a number of decimal places. If you choose
this option, a new eld appears for you to enter the number of decimal places.
For example, 123.456789 becomes 123.46 in Fixed 2 format.
●
Scientic—Displays results with an one-digit exponent to the left of the decimal
point, and the specied number of decimal places. For example, 123.456789
becomes 1.23E2 in Scientic 2 format.
●
Engineering—Displays results with an exponent that is a multiple of 3, and the
specied number of signicant digits beyond the rst one. Example: 123.456E7
becomes 1.23E9 in Engineering 2 format.
Entry
●
Textbook—An expression is entered in much the same way as if you were
writing it on paper (with some arguments above or below others). In other words,
your entry could be two-dimensional.
●
Algebraic—An expression is entered on a single line. Your entry is always one-
dimensional.
●
RPN—Reverse Polish Notation. The arguments of the expression are entered
rst followed by the operator. The entry of an operator automatically evaluates
what has already been entered.
