Name return Examples int val = 30; void setup() { Serial.begin(9600); } void loop() { int t = timestwo(val); Serial.println(t); // prints 60 } int timestwo(int dVal) { dVal = dVal * 2; return dVal; } Description Keyword used to indicate the value to return from a function. The value being returned must be the same datatype as defined in the function declaration. Functions declared with void can't return values and shouldn't include a return value. The keyword return may also be used to break out of a function thus not allowing the program to read the remaining statements (see the third example above). Syntax typefunction { statements return value } Parameters type boolean, byte, char, int, float, String, boolean[], byte[], char[], int[], float[] function any function that is being defined statements any valid statements value must be the same datatype as the type parameter Usage Application Updated on September 16, 2010 09:16:47pm PDT Wiring is an open project initiated by Hernando Barragán. It is developed by a small team of volunteers. © Info, Processing © Info
