谢谢你的帮助

Answer 1

修复'round'和'roundf'错误替换(第103和110行):

static double round(double num)
static float roundf(float num)

有:

static inline double round(double num)
static inline float roundf(float num)

要修复"signbit"错误,请使用以下宏(第128行)将其括起来:

#if _MSC_VER < 1800
inline bool signbit(double num) { return _copysign(1.0, num) < 0; }
#endif

使用VS 2013兼容性的官方补丁.
