Wren has built-in constants for infinity and NaN though they can also be generated from 'normal' 64 bit floating point values which is the underlying type of all numbers in Wren.
Note that when using the built-in operators NaN's never compare equal, even to themselves. Also, internally, Wren generates several different NaN values but the value returned by the built-in constant ''Num.nan'' is always the minimum 'quiet' NaN whose bit
