CopySign(float, float)

Copies the sign of a value to the sign of another value (将一个值的符号复制到另一个值).

public static float CopySign(float value, float sign)

Parameters

value float

The value whose magnitude is used in the result (结果中使用的幅度).

sign float

The value whose sign is used in the result (结果中使用符号的值).

Returns

float

A value with the magnitude of value and the sign of sign (根据 value的幅度和sign的符号而生成的值).

Remarks

No exception is thrown. For the MinValue of integer types, the source value is returned.(不会抛出异常. 对于整数类型的 MinValue, 会返回源值).

But CopySign_Bcl behaves differently. Throws an exception for the MinValue of integer types (而 CopySign_Bcl 的行为有所不同. 对于整数类型的 MinValue, 会抛出异常): System.OverflowException : Negating the minimum value of a twos complement number is invalid.
