public class ScientificFormat
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, INumberFormat, INumberFormatOperations, IScientificNumberFormat, IClone, IPersist, IPersistStream, Externalizable

An object for formatting numbers in a scientific format.

Description

ScientificFormat is an IScientificNumberFormat interface coclass who's members determine how the ValueToString method in the associated INumberFormat interface formats numbers.

Use the ScientificFormat when you want to express numbers in a scientific format, for example to create a table of empirical values. ScientificFormat expresses numbers as a power of 10. For example, the value 1500 scientifically formatted to 3 significant digits is the expression 1.50e+003, where the number before 'e' is the mantissa, and the number after 'e' is the power of 10, or exponent. The meaning of this expression is 1.50 X 10^3. The number of digits in exponent (+003) cannot be changed and is always a plus or minus sign and 3 digits.

The DecimalPlaces property sets or returns a long representing the number of decimals to show in the mantissa. Since all digits in a scientific format expression are significant, set the DecimalPlaces property to the number of desired significant digits minus 1. For example, to express the value 1 to 3 significant digits (1.00e+000), set DecimalPlaces to 2. The default value is 6.

Remarks

The power behind the scientific format is a way of expressing significant zeros. For example, a 1000 yard distance measured with a bicycle odometer may only be accurate to the nearest 10th mile (176 yards). In this case, 1000 is only significant to one place and should be expressed as 1 X 10^3. On the other hand, you may know the measurement is precise to the last zero (perhaps you carefully measured this distance with a yardstick); you would then want to express the measurement as 1.000 X 10^3.

Constructor Detail

ScientificFormat

public ScientificFormat()
                 throws IOException,
                        UnknownHostException

Constructs a ScientificFormat using ArcGIS Engine.

Throws:

IOException - if there are interop problems

UnknownHostException - if there are interop problems

ScientificFormat

public ScientificFormat(Object obj)
                 throws IOException

Deprecated. As of ArcGIS 9.2, replaced by normal Java casts.
ScientificFormat theScientificFormat = (ScientificFormat) obj;

Construct a ScientificFormat using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to ScientificFormat.

Parameters:

obj - an object returned from ArcGIS Engine or Server

Throws:

IOException - if there are interop problems

Method Detail

getClsid

public static String getClsid()

getClsid.

equals

public boolean equals(Object o)

Compare this object with another

Overrides:

equals in class Object

hashCode

public int hashCode()

the hashcode for this object

Overrides:

hashCode in class Object

valueToString

public String valueToString(double value)
                     throws IOException,
                            AutomationException

Converts a numeric value to a formatted string.

Description

The ValueToString method expresses a numeric value as a formatted string. The string is formatted based on the property settings of the number formatting interface that is used. See the particular number formatting interface you're interested in under See Also above for more information.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:

valueToString in interface INumberFormat

Parameters:

value - The value (in)

Returns:

The str

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

stringToValue

public double stringToValue(String str)
                     throws IOException,
                            AutomationException

Converts a formatted string to a numeric value.

Description

The StringToValue method obtains a numerical value from a formatted string. The string doesn't necessarily need to have been formatted with the ValueToString method, but the string needs to look like it would be if it was formatted with the associated interface's implementation of the ValueToString method. See the particular number formatting interface you're interested in under See Also above for more information.

Remarks

When using the StringToValue method to obtain a ValueToString argument value, the properties in the associated interface must be set the same as they were when the ValueToString method was used. This applies in cases where ValueToString may perform a numerical conversion (in the IAngleFormat, IFractionFormat, IPercentageFormat, and IRateFormat interfaces).

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:

stringToValue in interface INumberFormat

Parameters:

str - The str (in)

Returns:

The value

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

increment

public double increment(double value)
                 throws IOException,
                        AutomationException

Increments a value according to the numbers format.

Remarks

The Increment method reacts differently depending on the number format object used and how that object is configured. A NumericFormat configured for a specific number of decimal places will increment to the last decimal place. For example, if two decimal places are specified, 22.533 would increment to 22.54; if the object is configured for two significant digits, 22.533 would increment to 24. For an AngleFormat, the input value is converted to the display format first then the same rules apply as for a NumericFormat.
