bool

This function will attempt to convert a given value into a boolean data type, where the value will be returned as true if it is greater than 0.5 and false otherwise.

Syntax:

bool(n);

Returns:

Boolean

Example:

if !is_bool(val)
   {
   val = bool(val);
   }

The above code checks the variable "val" to see if it is a boolean and if it is not then it is converted to one.
