| - | ====== Using expressions to create a dynamic watchface ====== | ||
| - | Use operators, mathematical functions or conditional statements to build a more dynamic watchface. | ||
| - | ===== Built-in operators ===== | ||
| - | Watchface Builder supports followind operators: | ||
| - | * Addition: 2 + 2 | ||
| - | * Subtraction: | ||
| - | * Multiplication: | ||
| - | * Division: 2 / 2 | ||
| - | * Exponentation: | ||
| - | * Unary Minus,Plus (Sign Operators): +2 - (-2) | ||
| - | * Modulo: 2 % 2 | ||
| - | |||
| - | ===== Mathematical Functions ===== | ||
| - | You can also use mathematical functions for your expression. These expressions are supported: | ||
| - | |||
| - | * abs: absolute value | ||
| - | * acos: arc cosine | ||
| - | * asin: arc sine | ||
| - | * atan: arc tangent | ||
| - | * cbrt: cubic root | ||
| - | * ceil: nearest upper integer | ||
| - | * cos: cosine | ||
| - | * cosh: hyperbolic cosine | ||
| - | * exp: euler' | ||
| - | * floor: nearest lower integer | ||
| - | * log: logarithmus naturalis (base e) | ||
| - | * log10: logarithm (base 10) | ||
| - | * log2: logarithm (base 2) | ||
| - | * sin: sine | ||
| - | * sinh: hyperbolic sine | ||
| - | * sqrt: square root | ||
| - | * tan: tangent | ||
| - | * tanh: hyperbolic tangent | ||
| - | |||
| - | ==== Example ==== | ||
| - | < | ||
| - | Returns the integer value for the current temperature | ||
| - | |||
| - | ===== Conditional statements | ||
| - | You can use condition statements. The syntax is: | ||
| - | |||
| - | < | ||
| - | |||
| - | Following operators are supported for a condition: | ||
| - | * greater equal >= | ||
| - | * lower equal <= | ||
| - | * lower < | ||
| - | * greater > | ||
| - | * equals == | ||
| - | * not equals != | ||
| - | |||
| - | ==== Example ==== | ||
| - | For example if you want a blinking watchface layer set following expression on your opacity property. | ||
| - | |||
| - | < | ||
| - | |||
| - | Every time the seconds value changes and the value divided by two gives no rest, the layer will be displayed. | ||
