 \emph{Number} represents real (double-precision floating-point or \emph{actually rational}) numbers. Operations on numbers follow the same rules of the underlying virtual machine\footnote{if you are not a computer person, just disregard}, and such machines must follow the IEEE 754 standard\footnote{ditto.}. 
 
-\emph{Boolean} is the type of the values that is either \textbf{TRUE} or \textbf{FALSE}. \textbf{number 0} and \textbf{FALSE} makes condition \emph{false}. When used in numeric context, \textbf{FALSE} will be interpreted as 0 and \textbf{TRUE} as 1.

 \emph{String} represents immutable\footnote{cannot be altered directly} sequences of bytes. However, you can't weave them to make something like \emph{string array}\footnote{future feature\ldots maybe\ldots? Probably not\ldots}.
