<h2>Binary and Unary Operators</h2>
<p class="PlainText">There are two types of operators in PBASIC, binary operators which require two arguments (such as the addition operator in 2 + 3) and unary operators which require one argument (such as the negate operator in -5). All the PBASIC operators are shown below, grouped under binary operators or unary operators. Click on any operator to see a full description on the Binary Operator or Unary Operator page.</p>
<h2>Notes about the 16-bit workspace</h2>
<p class="PlainText">Many of the operator descriptions will say something like "computes (some function) of a 16-bit number." This does not mean that the operator does not work on smaller byte or nibble values, but rather that the computation is done in a 16-bit workspace. If the value is smaller than 16 bits, the BASIC Stamp pads it with leading 0s to make a 16-bit value. If the 16-bit result of a calculation is to be packed into a smaller variable, the higher-order bits are discarded (truncated).</p>
