SignFloat(float)
Computes the sign of a value and returns a floating point number (计算值的符号并返回浮点数).
public static float SignFloat(float value)Parameters
valuefloatThe value whose sign is to be computed (要计算其符号的值)
Returns
- float
Returns 1 if the value is positive, 0 if the value is zero, -1 if the value is negative, and
NaNif the value isNaN(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).
Remarks
No exception is thrown. For the NaN of float types, returns NaN.(不会抛出异常. 对于浮点类型的 NaN, 会返回 NaN).
