HP 39gs Graphing manual Setting a mode

Setting	Options (Continued)
	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.
