 ====== Argument ======
-An argument is defined as a value sent to a function, or to [[Expression|expressions]] or [[Lookup_table|lookup tables]].
+In mathematics, an argument of a function is a value provided to obtain the function's result. It is also called an independent variable.
-Different functions require different amounts of arguments;
+In the Ecolego an argument is defined as a value sent to a function, or to [[Expression|expressions]] or [[Lookup_table|lookup tables]].
-  * time() requires no arguments. You need therefore not write the parenthesis, but can call the function using only the name: time.
+Different functions require different amounts of arguments, examples:
-  * sin() requires one argument - the angle
-  * mod() requires two arguments - the value and the divider
+  * time() requires no arguments. You need therefore not write the parenthesis, but can call the function using only the name: time. Returns the current simulation time in the simulation time unit.
+  * sin() requires one argument - the angle. Returns the trigonometric sine of an angle.
+  * abs() requires one argument - the value, or parameter/expression name to return its absolute value.
+  * mod() requires two arguments - the dividend and the divider. The function helps find a remainder after a number (dividend) is divided by another number (divisor).
   * max() requires two, //or more//, arguments and will return the highest of the given arguments.
   * A [[Lookup_table|lookup table]] which has been configured to accept arguments accepts only one argument - the lookup key.
