Method Detail

castToShort

public static short castToShort(double d)

Casts a double value to a short value, taking into account and eliminating overflow problems.

Parameters:

d - the double to cast to a short

Returns:

The cast short. If the argument double is smaller than the Short.MIN_VALUE then the Short.MIN_VALUE is returned. If the argument double is larger than the Short.MAX_VALUE then the Short.MAX_VALUE is returned.

castToByte

public static byte castToByte(double d)

Casts a double value to a byte value, taking into account and eliminating overflow problems.

Parameters:

d - the double to cast to a byte

Returns:

The cast byte. If the argument double is smaller than the Byte.MIN_VALUE then the Byte.MIN_VALUE is returned. If the argument double is larger than the Byte.MAX_VALUE then the Byte.MAX_VALUE is returned.

castToLong

public static long castToLong(double d)

Casts a double value to a long value, taking into account and eliminating overflow problems.

Parameters:

d - the double to cast to a long

Returns:

The cast long. If the argument double is smaller than the Long.MIN_VALUE then the Long.MIN_VALUE is returned. If the argument double is larger than the Long.MAX_VALUE then the Long.MAX_VALUE is returned.

castToInt

public static int castToInt(double d)

Casts a double value to a int value, taking into account and eliminating overflow problems.

Parameters:

d - the double to cast to a short

Returns:

The cast int. If the argument double is smaller than the Integer.MIN_VALUE then the Int.MIN_VALUE is returned. If the argument double is larger than the Integer.MAX_VALUE then the Int.MAX_VALUE is returned.
