MathFunctions

quantities math

Mixin template that introduces math functions operating on a quantity of value type N in the current scope. Each function imports module_ internally. This module should contain the math primitives that can operate on the variables of type N, such as sqrt, cbrt, pow and fabs.

mixin template MathFunctions (
N
string module_ = "std.math"
) {
auto square(U unit);
auto cubic(U unit);
auto pow(U unit);
auto sqrt(Q quantity);
auto cbrt(Q quantity);
auto nthRoot(Q quantity);
Q abs(Q quantity);
}

Examples

t
{
    enum meter = unit!("L");
    enum liter = 0.001 * meter * meter * meter;

    mixin MathFunctions!(real, "std.math");

    auto surface = 25 * square(meter);
    auto side = sqrt(surface);
    assert(side.value(meter).approxEqual(5));

    auto volume = 27 * liter;
    side = cbrt(volume);
    assert(side.value(meter).approxEqual(0.3));

    auto delta = -10 * meter;
    assert(abs(delta) == 10 * meter
