Table 4-1. Ski Simulator Arithmetic and Logic Operators

Operator	Description
( )	group operators with operands
! ~ + - *	opposite truth value, logical one’s complement,
	unary plus, unary minus, dereference: treat as an
	address and read eight bytes
* /	multiply, divide
+ -	add, subtract
<< >>	logical left shift, logical right shift
< <= > >=	less than, less than or equal to, greater than, greater
	than or equal to
== !=	equal to, not equal to
&	bitwise and
^	bitwise exclusive or
	bitwise or
&&	logical and
	logical or

As an example, in xski,

eval 64 0d64 0o64 0b100000 *main ~(((0D1234+0X10EF0)*4)<<6)+0B10001001

prints the values of the six expressions in the Main Window, as shown in Figure 4-1.The first expression is taken as a hexadecimal number, the second as a decimal number, the third as an octal number, and the fourth as a binary number. The fifth expression is the value at the location specified by the symbol “ main” (the first 64 bits of the code bundle at that loca- tion), and the sixth expression is the result of some arithmetic.
