Method YSignFloat

Determine the sign of each element and returns a floating point number (判断各个元素的符号并返回浮点数). Mnemonic: rt[i] := signFloat(value[i]).

public static Vector<float> YSignFloat(Vector<float> value)

Vector<float>: A vector whose elements depend on the sign of the corresponding element of value: Returns 1 if the value is positive, 0 if the value is zero, -1 if the value is negative, and NaN if the value is NaN (一个向量，其元素取决于value的对应元素的符号情况: 值为正数时返回1, 值为0时返回0, 值为负数时返回-1, 值为NaN时返回NaN).

public static Vector<double> YSignFloat(Vector<double> value)

Vector<double>: A vector whose elements depend on the sign of the corresponding element of value: Returns 1 if the value is positive, 0 if the value is zero, -1 if the value is negative, and NaN if the value is NaN (一个向量，其元素取决于value的对应元素的符号情况: 值为正数时返回1, 值为0时返回0, 值为负数时返回-1, 值为NaN时返回NaN).
