(:Summary: Basic information usable in Formulas. :)

A '''value''' is the basic information usable in QDR Formulas. It can be expressed as a number (like "@@10@@") or can be the result of an operation (like "@@3 + 5@@"), or the result of a function (like "@@max(d6,d6)@@").

A value can hold up to three decimal values, but all the decimals are truncated in the final result (i.e. the formula "@@(2/3)+0.5@@" returns @@1@@ and the formula "@@rup((2/3)+0.5)@@" will obviously return @@2@@).

Each value in QDR is composed by a ''numeric'' (shown as the numeric result) and a ''label'' (shown as the extended result).

Let’s take in example the addition. It take two operands (right and left) that are two distinct values and generates a new value whose ''numeric'' is the sum of the ''numerics'' of the operands, and the ''label'' is the concatenation of the operands' ''labels'' separated by "@@ + @@". Thus, the formula "@@3 + 2@@" will sum two values: first value is composed by the ''numeric'' @@3@@ and the ''label'' "@@3@@", second value is composed by the ''numeric'' @@2@@ and the ''label'' "@@2@@". The result of the addition will be a new value composed by the ''numeric'' @@5@@ and the ''label'' "@@3 + 2@@".

[[Qdr/FunctionsGuide|Functions]] and [[Qdr/OperatorsGuide|operators]] works with ''numerics'' and ''labels'' and each one generates a new '''value''', whose ''numeric'' and ''label'' depends on the operation performed by the operator or the function.
