# Math.Max Method (Double, Double)

.NET Framework (current version)

Note

The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

Returns the larger of two double-precision floating-point numbers.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

## Syntax

```public static double Max(
double val1,
double val2
)
```

#### Parameters

val1
Type: System.Double

The first of two double-precision floating-point numbers to compare.

val2
Type: System.Double

The second of two double-precision floating-point numbers to compare.

#### Return Value

Type: System.Double

Parameter val1 or val2, whichever is larger. If val1, val2, or both val1 and val2 are equal to NaN, NaN is returned.

## Examples

The following example demonstrates how to use the Max method to return and display the greater of two variables.

```// This example demonstrates Math.Max()
using System;

class Sample
{
public static void Main()
{
string str = "{0}: The greater of {1,3} and {2,3} is {3}.";
string nl = Environment.NewLine;

byte     xByte1    = 1,    xByte2    = 51;
short    xShort1   = -2,   xShort2   = 52;
int      xInt1     = -3,   xInt2     = 53;
long     xLong1    = -4,   xLong2    = 54;
float    xSingle1  = 5.0f, xSingle2  = 55.0f;
double   xDouble1  = 6.0,  xDouble2  = 56.0;
Decimal  xDecimal1 = 7m,   xDecimal2 = 57m;

// The following types are not CLS-compliant.
sbyte    xSbyte1   = 101, xSbyte2  = 111;
ushort   xUshort1  = 102, xUshort2 = 112;
uint     xUint1    = 103, xUint2   = 113;
ulong    xUlong1   = 104, xUlong2  = 114;

Console.WriteLine("{0}Display the greater of two values:{0}", nl);
Console.WriteLine(str, "Byte   ", xByte1, xByte2, Math.Max(xByte1, xByte2));
Console.WriteLine(str, "Int16  ", xShort1, xShort2, Math.Max(xShort1, xShort2));
Console.WriteLine(str, "Int32  ", xInt1, xInt2, Math.Max(xInt1, xInt2));
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.
