chop - multiple declarations
Function chop
Replaces real numbers that are close to zero by exactly zero.

Function chop
Replaces all numbers in the given array that are close to zero by exactly zero. To chop the array in-place, pass the same array as both x and buffer.
Real[] chop(Real)
(
Real[] x,
real threshold = 1e-10L,
Real[] buffer = null
) nothrow
if (isFloatingPoint!Real);
double[] a = [1.0, 1e-20, 2.0];
double[] x = [1.0, 0.0, 2.0];
auto b = chop(a);
assert (b == x);
chop(a, 1e-12L, a);
assert (a == x);
