System.Math.Max 方法 (Double, Double)
方法描述
返回两个双精度浮点数字中较大的一个。
语法定义(C# System.Math.Max 方法 (Double, Double) 的用法)
public static double Max( double val1, double val2 )
参数/返回值
| 参数值/返回值 | 参数类型/返回类型 | 参数描述/返回描述 |
|---|---|---|
| val1 | System-Double | 要比较的两个双精度浮点数中的第一个。 |
| val2 | System-Double | 要比较的两个双精度浮点数中的第二个。 |
| 返回值 | System.Double | val1 或 val2 参数中较大的一个。 如果 val1 或 val2 或者 val1 和 val2 都等于 NaN，则返回 NaN。 |

Console.WriteLine(str, "Int64 ", xLong1, xLong2, Math.Max(xLong1, xLong2));
Console.WriteLine(str, "Single ", xSingle1, xSingle2, Math.Max(xSingle1, xSingle2));
Console.WriteLine(str, "Double ", xDouble1, xDouble2, Math.Max(xDouble1, xDouble2));
Console.WriteLine(str, "Decimal", xDecimal1, xDecimal2, Math.Max(xDecimal1, xDecimal2));
//
Console.WriteLine("{0}The following types are not CLS-compliant.{0}", nl);
Console.WriteLine(str, "SByte ", xSbyte1, xSbyte2, Math.Max(xSbyte1, xSbyte2));
Console.WriteLine(str, "UInt16 ", xUshort1, xUshort2, Math.Max(xUshort1, xUshort2));
Console.WriteLine(str, "UInt32 ", xUint1, xUint2, Math.Max(xUint1, xUint2));
Console.WriteLine(str, "UInt64 ", xUlong1, xUlong2, Math.Max(xUlong1, xUlong2));

/*
This example produces the following results:
Display the greater of two values:
Byte : The greater of 1 and 51 is 51.
Int16 : The greater of -2 and 52 is 52.
Int32 : The greater of -3 and 53 is 53.
Int64 : The greater of -4 and 54 is 54.
Single : The greater of 5 and 55 is 55.
Double : The greater of 6 and 56 is 56.
Decimal: The greater of 7 and 57 is 57.
(The following types are not CLS-compliant.)
SByte : The greater of 101 and 111 is 111.
UInt16 : The greater of 102 and 112 is 112.
UInt32 : The greater of 103 and 113 is 113.
UInt64 : The greater of 104 and 114 is 114.
