# Math.Min メソッド (Single, Single)

2013/12/12

2 つの単精度浮動小数点数のうち、小さい方を返します。

Namespace:  System
アセンブリ:  mscorlib (mscorlib.dll 内)

## 構文

```public static float Min(
float val1,
float val2
)
```

val1

val2

#### 戻り値

パラメーター val1 または val2 のいずれか小さい方。val1val2、または val1val2 の両方が NaN に等しい場合、NaN が返されます。

## 例

Min メソッドを使用して、2 つの単精度浮動小数点数型変数のうち小さい方の値を取得して表示する方法を次の例に示します。

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

class Example
{
public static void Demo(System.Windows.Controls.TextBlock outputBlock)
{
string str = "{0}: The lesser 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;

outputBlock.Text += String.Format("{0}Display the lesser of two values:{0}", nl) + "\n";
outputBlock.Text += String.Format(str, "Byte   ", xByte1, xByte2, Math.Min(xByte1, xByte2)) + "\n";
outputBlock.Text += String.Format(str, "Int16  ", xShort1, xShort2, Math.Min(xShort1, xShort2)) + "\n";
outputBlock.Text += String.Format(str, "Int32  ", xInt1, xInt2, Math.Min(xInt1, xInt2)) + "\n";
outputBlock.Text += String.Format(str, "Int64  ", xLong1, xLong2, Math.Min(xLong1, xLong2)) + "\n";
outputBlock.Text += String.Format(str, "Single ", xSingle1, xSingle2, Math.Min(xSingle1, xSingle2)) + "\n";
outputBlock.Text += String.Format(str, "Double ", xDouble1, xDouble2, Math.Min(xDouble1, xDouble2)) + "\n";
outputBlock.Text += String.Format(str, "Decimal", xDecimal1, xDecimal2, Math.Min(xDecimal1, xDecimal2)) + "\n";
//
outputBlock.Text += String.Format("{0}The following types are not CLS-compliant:{0}", nl) + "\n";
outputBlock.Text += String.Format(str, "SByte  ", xSbyte1, xSbyte2, Math.Min(xSbyte1, xSbyte2)) + "\n";
outputBlock.Text += String.Format(str, "UInt16 ", xUshort1, xUshort2, Math.Min(xUshort1, xUshort2)) + "\n";
outputBlock.Text += String.Format(str, "UInt32 ", xUint1, xUint2, Math.Min(xUint1, xUint2)) + "\n";
outputBlock.Text += String.Format(str, "UInt64 ", xUlong1, xUlong2, Math.Min(xUlong1, xUlong2)) + "\n";
}
}
/*
This example produces the following results:

Display the lesser of two values:

Byte   : The lesser of   1 and  51 is 1.
Int16  : The lesser of  -2 and  52 is -2.
Int32  : The lesser of  -3 and  53 is -3.
Int64  : The lesser of  -4 and  54 is -4.
Single : The lesser of   5 and  55 is 5.
Double : The lesser of   6 and  56 is 6.
Decimal: The lesser of   7 and  57 is 7.

The following types are not CLS-compliant:

SByte  : The lesser of 101 and 111 is 101.
UInt16 : The lesser of 102 and 112 is 102.
UInt32 : The lesser of 103 and 113 is 103.
UInt64 : The lesser of 104 and 114 is 104.
