- (subtraction) operator
| Type | Assocation | Precedence | Input types | Output types |
| binary | left | 4 | int float complex color | int float complex color |
This operator subtracts the second operand from the first operand and returns the result. The type of the result is equal to the largest type of the operands (complex is larger than float, and float is larger than int).
When used with color operands, the – operator returns a color where each component (red, green, blue, alpha) is the signed difference of the respective components from the operands.
Examples:
3 - 2 ; 1 3.15 - 9 ; -5.85 (3, 2) - (6, 4) ; (-3, -2) rgba(1, 0.4, 0.2, 1) - \ rgba(0.5, 0.49, 0.1, 1) ; rgba(0.5, -0.99, 0.1, 0)
