Nine binary operations are defined There are four basic mathematical operations addition subtraction multiplication and division There are three logical operations non exclusive or OR exclusive or XOR and logical and AND The eighth operation is the modulus operation MOD The ninth operation is the power operation of raising the number on the left of the operation to the power on the right The binary operations are divided into three groups The first group is power The second group is multiplication division and modulus The third group is addition subtraction logical non exclusive or logical exclusive or and logical and If operations are strung together for example in the expression 2 0 3 1 5 5 5 11 0 operations in the first group are to be performed before operations in the second group and operations in the second group before operations in the third group If an expression contains more than one operation from the same group such as the first and in the example the operation on the left is performed first Thus the example is equivalent to 2 0 3 1 5 5 5 11 0 which simplifies to 1 0 0 5 which is 0 5 12 September 2014 Release 4 01 104 EDINGCNC Manual The logical operations and modulus are to be performed on any real numbers not just on integers The number zero is equivalent to logical false and any non zero number is equivalent to logic
