Description

Subtracts one value from another and may also be used to negate a value. As a subtraction operator, the value of the second parameter is subtracted from the first. For example, 5 - 3 yields the number 2. As a negation operator, it is equivalent to multiplying a number by -1. For example, -5 is the same as 5 * ‑1.

Examples

  • int a = 5;         // Sets 'a' to 5 
int b = -a;        // Sets 'b' to -5 
int c = -(5 + 3);  // Sets 'c' to -8 

  • int c = 50 - 5;  // Sets 'c' to 45
int d = c - 5;   // Sets 'd' to 40
int e = d - 60;  // Sets 'e' to -20

Syntax

  • -value1
  • value1 - value2
