Note that Bool is an integer type and all the usual promotion rules and numeric operators are also defined on it. The short-circuiting operations are explained on the linked page. Negation changes true to false and vice versa. The following Boolean operators are supported on Bool types: Expression This is useful for preventing the propagation of NaN values in quantities that are known to be zero. When used in multiplication, false acts as a strong zero: julia> NaN * false For instance, we would generally write -x 2 to reflect that first x gets negated, and then 2 is added to that result.) (By convention, we tend to space operators more tightly if they get applied before other nearby operators. Here are some simple examples using arithmetic operators: julia> 1 2 3 See the manual section on Unicode input for more information. The ÷ sign can be conveniently typed by writing \div to the REPL or Julia IDE. See Conversion and Promotion for details of the promotion system. Julia's promotion system makes arithmetic operations on mixtures of argument types "just work" naturally and automatically. See Numeric Literal Coefficients for details. 2x or 2(x y), is treated as a multiplication, except with higher precedence than other binary operations. The following arithmetic operators are supported on all primitive numeric types: ExpressionĪ numeric literal placed directly before an identifier or parentheses, e.g. Julia provides a complete collection of basic arithmetic and bitwise operators across all of its numeric primitive types, as well as providing portable, efficient implementations of a comprehensive collection of standard mathematical functions.
