approxEqual

Computes whether two values are approximately equal, admitting a maximum relative difference, and a maximum absolute difference.

bool

(

Complex!T lhs

Complex!T rhs

const T maxRelDiff = 0x1p-20f

const T maxAbsDiff = 0x1p-20f

)

Parameters

lhs Complex!T: First item to compare.
rhs Complex!T: Second item to compare.
maxRelDiff T: Maximum allowable difference relative to rhs. Defaults to 0.5 ^^ 20.
maxAbsDiff T: Maximum absolute difference. Defaults to 0.5 ^^ 20.

Type: bool

true if the two items are equal or approximately equal under either criterium.

Complex types works as approxEqual(l.re, r.re) && approxEqual(l.im, r.im)

assert(approxEqual(complex(1.0, 1), complex(1.0000001, 1), 1.0000001));
assert(!approxEqual(complex(100000.0, 0), complex(100001.0, 0)));
