Arithmetic

see arithmetic operations

• calculation:
  • Number + Number: addition
  • - Number: returns the opposite sign of a number
  • Number - Number: subtraction
  • Number * Number: multiplcation
  • Number / Number: floating-point division
  • Number ^ Power: raises Number to the power Power
  • Number \ Number: (DIV) - integer division; A \ B = Int(A / B)
  • Number MOD Number: modulo
• comparison:
  • Number = Number: TRUE if two numbers are equal
  • Number <> Number: TRUE if two numbers are different
  • Number1 < Number2: TRUE if Number1 is strictly lower than Number2
  • Number1 > Number2: TRUE if Number1 is strictly greater than Number2
  • Number1 <= Number2: TRUE if Number1 is lower or equal than Number2
  • Number1 >= Number2: TRUE if Number1 is greater or equal than Number2
  • When a comparison result is assigned to an integer variable, TRUE = -1 and FALSE = 0.

Assignment

see assignment operators

• Variable = Expression: Direct assignment
• Variable += Expression: Assignment with addition (not available in Gambas 1.0.18)
• Variable -= Expression: Assignment with subtraction (not available in Gambas 1.0.18)
• Variable *= Expression: Assignment with multiplication (the rest of these are probably also not available in v1.0.18)
• Variable /= Expression: Assignment with division
• Variable \= Expression: Assignment with integer division (V = V \ E)
• Variable &= Expression: Assignment with string concatenation (V = V & E)
• Variable &/= Expression: Assignment with path concatenation (V = V &/ E)

Logical

see logical operators

String

see string operators

• String & String: concatenation of two strings
• String &/ String: concatenation of two strings containing file path parts; add a path separator if neither is empty
• String = String: strings are equal?
• String == String: strings are equal? (case-insensitive)
• String LIKE String: string matches a pattern?
• String <> String: strings are different?
• String1 < String2: String1 is "strictly lower" than String2?
• String1 > String2: String1 is "strictly greater" than String2?
• String1 <= String2: String1 is "lower than" or equal to String2?
• String1 >= String2: String1 is "greater than" or equal to String2?
