Negation
Negation (Ì) returns the negative of value. You can use M with real or complex numbers, expressions,
lists, and matrices. For subtraction, use ¹.
M
value
EOS™ rules (Chapter 1) determine when negation is evaluated. For example, L4
2
returns a negative
number, because squaring is evaluated before negation. Use parentheses to square a negated number,
as in
(L4)
2
.
Note: The negation symbol (M) is shorter and higher than the subtraction sign (N), which is displayed
when you press ¹.
Pi
p (Pi, y B) is stored as a constant. In calculations, 3.1415926535898 is used for p.
