Elmo HARmonica Logical not, Unary Minus, Bitwise Left Shift and Right Shift operators

HARSFEN0602ElmoHARmonicaSoftwareManual			PRELIMINARYDRAFT
Notation
Description	Logical OR. The result is 1 if any of the arguments is nonzero, 0 if both are zero.
	The arguments are not truncated to integers before evaluations
Number of	2
arguments
Output type	0 or 1
Example	1	0 yield 1
	0	0 is 0.

4.2.4.18Logical NOT

Notation	!
Description	Logical NOT. The result is 1 if the argument is zero, and 0 else
	The arguments are not truncated to integers before evaluations
Number of	1
arguments
Output type	0 or 1
Example	!4 yields 0
	!0 yields 1
	!0.0004 yields 1

4.2.4.19Unary Minus

Notation	-
Description	Unary MINUS. The result is negative if the argument is positive, and vise
	versa.
	The arguments are not truncated to integers before evaluations
Number of	1
arguments
Output type	The same as argument
Example	-4.5 yields –4.5
	-4 yields –4
	(-4) yields 4
	-5+5 yields 0

4.2.4.20Bitwise Left Shift and Right Shift operators

Notation	<< or >>
Description	The bitwise shift operators shift their first operand left (<<) or right (>>) by the
	number of positions the second operand specifies.
	The arguments are truncated to integers before evaluations.
Number of	2
arguments
Output type	32 bit long integer.
Example	8>>2 yields 2
	8<<2 yields 32
