Vipsi command syntax: Operators
Operators
Glossary: OperatorOperators are typically special characters Operators: Boolean Or with Variable "||="
Operators: Bitwise Or with Variable "|="
Operators: Bitwise Or "|"
Operators: Boolean Or "||"or tupels, sometimes even triples of Flow control: if … then
Flow control: try … thenthem. List functions: thisThis is because our ancestors liked to omit separating spaces Operators: Boolean And with Variable "&&="
Operators: Bitwise And with Variable "&="
Operators: Bitwise And "&"
Operators: Boolean And "&&"and so Vipsi command syntax: Operators
Operators
Glossary: Operatoroperators had to be self-separating from their Vipsi command syntax: Arguments

Most Vipsi command syntax: Operators
Operators
Glossary: Operatoroperators are diadic, which means, they need two Glossary: Operator
Glossary: Operandoperands, one Glossary: Operator
Glossary: Operandoperand written to Flow control: if … then
Flow control: try … thenthe left Operators: Boolean And with Variable "&&="
Operators: Bitwise And with Variable "&="
Operators: Bitwise And "&"
Operators: Boolean And "&&"and one to Flow control: if … then
Flow control: try … thenthe right sides. Some are monadic, requiring only one Glossary: Operator
Glossary: Operandoperand, Operators: Boolean And with Variable "&&="
Operators: Bitwise And with Variable "&="
Operators: Bitwise And "&"
Operators: Boolean And "&&"and to make it more difficult, they may stand before (prefix) Operators: Boolean Or with Variable "||="
Operators: Bitwise Or with Variable "|="
Operators: Bitwise Or "|"
Operators: Boolean Or "||"or behind (postfix) their Glossary: Operator
Glossary: Operandoperand.

As a real od man out there is also a Operators: Select "? :"triadic operator. Guess which. ;-)

Some examples:

a * 2 + 47          // Vipsi command syntax: Operators
Operators
Glossary: Operatoroperators: * +
i++ + ++a           // ++ + ++
47*100 + 11         // * +
a[1] + a[2] + a[3]  // + +
f = a>0             // = >
