This section isn't intended to cover every function or expression Mendix has to offer. 1 Overview The starts-with() function tests whether a string attribute starts with a specific string (case-insensitive) as a sub-string. To accomplish this, we will utilize the two microflow functions below: Round – Rounding a floating-point number, optionally to a specified precision Floor – Rounding a floating-point number down. Calculate the average time to complete a task, then round that number down so the end result is the average time minute value. Its result should be an enumeration or a boolean and it can be used in an exclusive split to make a decision based on that result. 0. The TrimTo… functions help you to trim any date/time value to the desired value. See Microflow Element Common Properties for properties that all microflow activities share (for example, caption). Make sure the microflow to be executed has an input parameter with data type Object and entity Queue. 1 Introduction The Cast object activity is used in a microflow after an object type decision to change the type of object from the generalized object type to the specialized object type of the path out of the object type decision.
