Math operators

 
  • Mathematical expressions are entered in the mathematical notation

  • An expression can include numbers, variable, operators, and functions

  • The math operators have different priority, which determines the order of their calculation

  • The following list shows the priority levels of the math operators

  • Within a priority group, "RedCrab" evaluates functions from left to right

  • Calculations within a pair of parentheses are evaluated first

  1. ∙, /, DIV, MOD, AND    
  2. +, -, OR, XOR    
  3. <, >, ≤, ≥, ≡, ≠    

 

         
Arithmetic operators   keyboard input
         
  = x = 3 assigning of a value  
  = 9 + 3 = 12 display of the result  
  + 9 + 3 = 12 addition  
  - 9 - 3 = 6 subtraction  
  9 ∙ 3 = 27 multiplication *
  / 9 / 3 = 3 division  
  Div 9 Div 4 = 2 integer division with remainder  
  Mod 9 Mod 4 = 1 remainder of an integer division  
         
Bit Operators    
         
  And 9 And 3 = 1 bitwise »and«  
  Or 9 Or 3 = 11 bitwise »or«  
  Xor 9 Xor 3 = 10 bitwise »exclusive or«  
         
Boolsche operators    
         
  < 9 < 3 = 0 less than  
  > 9 > 3 = 1 greater than  
  9 ≤ 3 = 0 less or equal than <=
  9 ≥ 3 = 1 greater or equal than >=
  9 ≡ 3 = 0 is equal ==
  9 ≠ 3 = 1 is not equal <>
         
  • The Boolean operators compare two real values and get the value one (if true) or the value zero (if false) as result

  • ! For Boolean comparison, the math operators can be applied only on real numbers

  • The Boolean operators have another function if they are applied with lists

  • Read the description of Pick
