HP 39gs Graphing manual Constants, Conversions, Maxreal, Minreal, →Cm

Constants

	The constants available from the MATH FUNCTIONS
	menu are mathematical constants. These are described in
	this section. The hp 39gs has two other menus of
	constants: program constants and physical constants.
	These are described in “Program constants and physical
	constants” on page 13-24.
e	Natural logarithm base. Internally represented as
	2.71828182846.
	e
i	Imaginary value for –1 , the complex number (0,1).
	i
MAXREAL	Maximum real number. Internally represented as
	9.99999999999 x 10499.
	MAXREAL
MINREAL	Minimum real number. Internally represented as
	1x10-499.
	MINREAL
π	Internally represented as 3.14159265359.
	π

Conversions

	The conversion functions are found on the Convert
	menu. They enable you to make the following
	conversions.
→C	Convert from Fahrenheit to Celcius.
	Example
	→C(212) returns 100
→F	Convert from Celcius to Fahrenheit.
	Example
	→F(0) returns 32
→CM	Convert from inches to centimeters.
