Short Description:	<Meta-HTML> contains a small set of commands for operating on numerical quantities. All of the arithmetic operators described in this section can accept a number, or simply the name of a variable, which is then looked up as if it had been written with <example code><get-var-once ...></example>. That is to say: <example> <set-var total = <add <get-var-once subtotals[0]> <get-var-once subtotals[current]>>> </example> can be written as: <example> <set-var total = <add subtotals[0] subtotals[current]>> </example>
Long Description:	The binary arithmetic operators always expect two arguments, and will produce a warning message in <funref DEBUGGING-COMMANDS DEBUGGING-OUTPUT> when given too few arguments. You can perform floating point arithmetic if one or both of the arguments is already a floating point number: <example> <div 10 3> --> 3 <div 10.0 3> --> 3.33 </example>
