X xor Catalog > BooleanExpr1 xor BooleanExpr2 ⇒ Boolean expression Returns true if BooleanExpr1 is true and BooleanExpr2 is false, or vice versa. Returns false if both arguments are true or if both are false. Returns a simplified Boolean expression if either of the arguments cannot be resolved to true or false. Note: See or, page 57. Integer1 xor Integer2 ⇒ integer Compares two real integers bit-by-bit using an xor operation. Internally, both integers are converted to signed, 64-bit binary numbers. When corresponding bits are compared, the result is 1 if either bit (but not both) is 1; the result is 0 if both bits are 0 or both bits are 1. The returned value represents the bit results, and is displayed according to the Base mode. In Hex base mode: Important: Zero, not the letter O. In Bin base mode: You can enter the integers in any number base. For a binary or hexadecimal entry, you must use the 0b or 0h prefix, respectively. Without a prefix, integers are treated as decimal (base 10). Note: A binary entry can have up to 64 digits (not counting the 0b prefix). A hexadecimal entry can have up to 16 digits. If you enter a decimal integer that is too large for a signed, 64-bit binary form, a symmetric modulo operation is used to bring the value into the appropriate range. Note: See or, page 57. Z zInterval zInterval s,List[,Freq[,CLevel]] (Data list input) zInterval s,v,n [,CLevel] (Summary stats input) Computes a z confidence interval. A summary of results is stored in the stat.results variable. (See page 76.)
