is_bool

is_bool(n);


Arguments:

Argument Description
n The argument to check.

Boolean


Example:

if is_bool(val)
   {
   global.Sound = val;
   }
else    {
   global.Sound = true;
   }

The above code checks the variable "val" to see if it is a real number and if it is it then uses it to set a global variable.
