    The word scalar derives from the Latin word scalaris, an adjectival form of scala (Latin for "ladder") The English word "scale" also comes from scala Source A Scalar is a variable that holds an individual value For example: Scalar Variable: Say that you are trying to represent the names of various students as a set of variables Each of the
  • What are the scalar fields and composite fields in JAVA?
    The terms 'scalar type' or 'scalar field' are usually used to contrast them with compound types fields A compound type is easiest to define and it is a type that contains multiple distinct elements These elements can have the same type, in which case the compound is an array or a list, or different types, in which case the compound is
  • Recommended generic approach to checking scalar field presence in . . .
    Use normal scalar fields with no presence tracking by default, and use fields with explicit presence tracking (e g optional) only where needed Generally it means that if we want all the use cases above to work, we can use no presence tracking if zero is not in a valid domain of a field, and use explicit presence tracking otherwise
  • Should you ever mix scalar and list contexts anyway?
    In scalar context, it returns the one value of that list that you probably want if you only want one value That's the UID of the named user There's no rule that governs what a particular thing will do in scalar context other than giving you the value that most people probably want
  • data structures - How to represent a set in JSON? - Software . . .
    Take a scalar, say 0 or null and force it to be the value of every key in the map: {"a": 0, "b": 0} This way, under standard comparison tools, the objects are equal, even if the key ordering is changed However, this technique pollutes the JSON document with irrelevant data [4] - As an ordered list
  • What is meant by a primitive data type?
    For example, in languages like C and C++, you have a number of built-in scalar types - int, float, double, char, etc These are "primitive" in the sense that they cannot be decomposed into simpler components From these basic types you can define new types - pointer types, array types, struct types, union types, etc
  • performance - Why does expressing calculations as matrix . . .
    Using SIMD instructions (confusingly, this is also called "vectorization" but in a different sense than in the text quotes in the question) In essence, instead of 4 or 8 or so scalar arithmetic instructions, give the CPU one instruction that performs arithmetic on 4 or 8 or so registers in parallel This can literally make some calculations
  • Why exactly does Java not allow numeric conditionals like if(5 . . .
    1 The controlling expression of an if statement shall have scalar type Semantics 2 In both forms, the first substatement is executed if the expression compares unequal to 0 In the else form, the second substatement is executed if the expression compares equal to 0 If the first substatement is reached via a label, the second substatement is
  • math - Array Multiplication and Division - Software Engineering Stack . . .
    "On the other hand, it behaves exactly like vector multiplication by a scalar, so in that sense it is intuitive " I disagree with this sentence In mathematics, if k is a scalar and v is a vector, then k v is scalar-vector multiplication, but v k is undefined It's always scalar-vector multiplication, and never vector-scalar multiplication –
