巨大的数字而不是带有浮点数的 0

问题描述

有时我会遇到大量的数字，其中预期为 0：

-5.96046e-08、-2.98023e-08 ...

即使看起来不对，它仍然将其视为 0（或者可能未定义？）。谁能告诉我这是什么，如果是正常的，如何避免，...

for (int j = 0; j < samplesPerBlock; ++j)
{
    if (!jobDone)
    {
        job.amplitude =
            (job.elapsed <= job.attack) * (job.veLocity / job.attack * job.elapsed) +
            (job.elapsed > job.attack && job.elapsed <= job.decay) * (job.veLocity - (job.veLocity - job.sustain) / (job.decay - job.attack) * (job.elapsed - job.attack)) +
            (job.elapsed > job.decay && job.on) * (job.sustain) +
            (!job.on && job.elapsed > job.decay) * (job.sustain - (job.sustain / job.release) * job.released);

        job.released += (!job.on && job.elapsed > job.decay);

        job.amplitude -= job.tochocke * (job.amplitude / job.chocke) * job.chocked;

        if (job.chocke == job.chocked)
        {
            jobDone = true;
            DBG(job.amplitude); // <- this is where I get those numbers
        }

        job.chocked += job.tochocke;
    }
}
