<h1 class="main">Appendix II: Operators</h1>
<p>This lists operators for <a href="v-types.html#primitive-types">primitive types</a> only.</p>
<p>Boolean values, including aliases of <code>bool</code> without an overloaded <code><</code> operator, cannot be ordered
with <code><</code>, <code>></code>, <code><=</code>, or <code>>=</code>. The checker currently does not enforce this restriction for
comparisons between generic operands specialized to <code>bool</code> or its aliases.</p>
<div class="language-v">+ sum integers, floats, strings

** power integers, floats
/ quotient integers, floats
% remainder integers
~ bitwise NOT integers

<p>Note: in V, <code>assert -10 % 7 == -3</code> passes. In programming, the sign of the remainder
depends upon the signs of divisor and dividend.
For calendar-style modular arithmetic, use floored division instead:
<code>math.divide_floored(-10, 7)</code> gives a quotient of <code>-2</code> with remainder <code>4</code>,
and <code>math.modulo_floored(-10, 7) == 4</code>. For floats, use <code>math.floor_div</code>
with <code>math.floor_mod</code>. New <code>//</code> and <code>%%</code> operators were considered, but <code>//</code>
would conflict with line comments, so these library functions are the
supported approach.</p>
