Sign(float)

Computes the sign of a value (计算值的符号).

public static int Sign(float value)

Parameters

value float

The value whose sign is to be computed (要计算其符号的值)

Returns

int

Returns 1 if the value is positive, 0 if the value is zero, and -1 if the value is negative (值为正数时返回1, 值为0时返回0, 值为负数时返回-1).

Remarks

No exception is thrown. For the NaN of float types, returns 0.(不会抛出异常. 对于浮点类型的 NaN, 会返回0).

But Sign_Bcl behaves differently. Throws an exception for the NaN of float types (而 Sign_Bcl 的行为有所不同. 对于浮点类型的 NaN, 会抛出异常): System.ArithmeticException: Function does not accept floating point Not-a-Number values.
