Julia uses similar binary operators for basic arithmetic operations as does mathematics or other programming languages. Most operators can be written in infix notation (that is, placed in between the values being computed). Julia has an order of operations that matches the common convention in mathe...

The remainder operator in Julia is the % operator. This operator behaves similarly to the % in languages such as C and C++. a % b is the signed remainder left over after dividing a by b. This operator is very useful for implementing certain algorithms, such as the following implementation of the Si...

Julia uses the standard mathematical meanings of arithmetic operations when applied to matrices. Sometimes, elementwise operations are desired instead. These are marked with a full stop (.) preceding the operator to be done elementwise. (Note that elementwise operations are often not as efficient as...
