# Convert.ToInt32 Method (Double)

.NET Framework 4

Converts the value of the specified double-precision floating-point number to an equivalent 32-bit signed integer.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
```public static int ToInt32(
double value
)
```

#### Parameters

value
Type: System.Double
The double-precision floating-point number to convert.

#### Return Value

Type: System.Int32
value, rounded to the nearest 32-bit signed integer. If value is halfway between two whole numbers, the even number is returned; that is, 4.5 is converted to 4, and 5.5 is converted to 6.
ExceptionCondition
OverflowException

value is greater than Int32.MaxValue or less than Int32.MinValue.

The following example attempts to convert each element in an array of Double values to an integer.

```
double[] values= { Double.MinValue, -1.38e10, -1023.299, -12.98,
0, 9.113e-16, 103.919, 17834.191, Double.MaxValue };
int result;

foreach (double value in values)
{
try {
result = Convert.ToInt32(value);
Console.WriteLine("Converted the {0} value '{1}' to the {2} value {3}.",
value.GetType().Name, value,
result.GetType().Name, result);
}
catch (OverflowException) {
Console.WriteLine("{0} is outside the range of the Int32 type.", value);
}
}
//    -1.79769313486232E+308 is outside the range of the Int32 type.
//    -13800000000 is outside the range of the Int16 type.
//    Converted the Double value '-1023.299' to the Int32 value -1023.
//    Converted the Double value '-12.98' to the Int32 value -13.
//    Converted the Double value '0' to the Int32 value 0.
//    Converted the Double value '9.113E-16' to the Int32 value 0.
//    Converted the Double value '103.919' to the Int32 value 104.
//    Converted the Double value '17834.191' to the Int32 value 17834.
//    1.79769313486232E+308 is outside the range of the Int32 type.
