Engineering. Displays result with an

 

exponent that is a multiple of 3, and

 

the specified number of significant

 

digits beyond the first one. Example:

 

123.456E7 becomes 1.23E9 in

 

Engineering 2 format.

 

Fraction. Displays results as fractions

 

based on the specified number of

 

decimal places. Examples:

 

123.456789 becomes 123 in

 

Fraction 2 format, and .333 becomes

 

1/3 and 0.142857 becomes 1/7.

 

See “Using fractions” on page 1-25.

 

Mixed Fraction. Displays results as

 

mixed fractions based on the specified

 

number of decimal places. A mixed

 

fraction has an integer part and a

 

fractional part. Examples:

 

123.456789 becomes 123+16/35

 

in Fraction 2 format, and 7÷ 3 returns

 

2+1/3. See “Using fractions” on

 

page 1-25.

Decimal

Dot or Comma. Displays a number

Mark

as 12456.98 (Dot mode) or as

 

12456,98 (Comma mode). Dot mode

 

uses commas to separate elements in

 

lists and matrices, and to separate

 

function arguments. Comma mode

 

uses periods (dot) as separators in

 

these contexts.

 

 

Setting a mode

This example demonstrates how to change the angle measure from the default mode, radians, to degrees for the current aplet. The procedure is the same for changing number format and decimal mark modes.
