FloatingPointComparison:C ++实现比较两个浮点数Li**烧喉 上传2KB 文件格式 zip 浮点比较 比较浮点数的功能。 计算机中的数字在内部用二进制表示,并且有些浮点数(例如0.1)没有用二进制精确表示。 如果没有精确的二进制表示形式,则该值将四舍五入到最接近的二进制表示形式,这将导致某些浮点数稍微不精确。 这种...
Doing a floating-point absolute epsilon check first, and then treating all other different-signed numbers as being non-equal is the simpler and safer thing to do. Here is some possible code for doing this, both for relative epsilon and for ULPs based comparison, with an absolute epsilon ‘sa...
