Math — math

Available: Stacks API v2

A virtual control to perform simple math. Most functions that math-controls provide can be more easily performed using template expressions. However, there are still a few ways that math-controls are useful, mostly in enable logic.

Math properties follow a two-argument, one-operator format: <argument_1> <operator> <argument_2> = <result>

Note: There is no enable property for the Math control. The Math control cannot be enabled (made visible) itself because a Math control is virtual – it has no user interface. A Math control also cannot be used to enable other controls. Math controls create dependencies between other controls: changes to the input values affect the output. This can create chains of dependency that take too long to evaluate, causing noticable lags in the Info Sidebar UI.


Argument 1

Arguments come in two formats. They can either be a constant number or a string that specifies the ID of some other control. If taking the value from another control, the other control must return a number typed value.


Argument 2

Arguments come in two formats. They can either be a constant number or a string that specifies the ID of some other control. If taking the value from another control, the other control must return a number typed value.


Operator

Operators have the standard C language functions.


Rounding

If the value of round is true, then the output number will be rounded to the nearest whole integer. If the round property is not present on a math function, then the default is to enable rounding.

Note: Rounding is enabled by default. To return a floating point value, you must include and disable rounding.
