net.sf.saxon.value.FloatValue
| FloatValue | | final public class FloatValue extends NumericValue (Code) | | A numeric (single precision floating point) value
|
| FloatValue | | public FloatValue(float value)(Code) | | Constructor supplying a float
Parameters:
value - the value of the float |
| convertPrimitive | | public AtomicValue convertPrimitive(BuiltInAtomicType requiredType, boolean validate, XPathContext context)(Code) | | Convert to target data type
Parameters:
requiredType - an integer identifying the required atomic type
Parameters:
context - an AtomicValue, a value of the required type; or an ErrorValue |
| effectiveBooleanValue | | public boolean effectiveBooleanValue(XPathContext context)(Code) | | Get the effective boolean value
Parameters:
context - true unless the value is zero or NaN |
| floatToString | | static CharSequence floatToString(float value, String javaString)(Code) | | Internal method used for conversion of a float to a string
Parameters:
value - the actual value
Parameters:
javaString - the result of converting the float to a string using the Java conventions.This value is adjusted as necessary to cater for the differences between the Java and XPath rules. the value converted to a string, according to the XPath casting rules. |
| getDoubleValue | | public double getDoubleValue()(Code) | | |
| getStringValue | | public String getStringValue()(Code) | | Get the value as a String
a String representation of the value |
| getStringValueCS | | public CharSequence getStringValueCS()(Code) | | Get the value as a String
a String representation of the value |
| getValue | | public float getValue()(Code) | | Get the value
|
| hashCode | | public int hashCode()(Code) | | Get the hashCode. This must conform to the rules for other NumericValue hashcodes
See Also: NumericValue.hashCode |
| isNaN | | public boolean isNaN()(Code) | | Test whether the value is the double/float value NaN
|
| isWholeNumber | | public boolean isWholeNumber()(Code) | | Determine whether the value is a whole number, that is, whether it compares
equal to some integer
|
| roundToHalfEven | | public NumericValue roundToHalfEven(int scale)(Code) | | Implement the XPath round-to-half-even() function
|
| schemaEquals | | public boolean schemaEquals(Value obj)(Code) | | Compare two values for equality. This supports identity constraints in XML Schema,
which allow list-valued elements and attributes to participate in key and uniqueness constraints.
This method returns false if any error occurs during the comparison, or if any of the items
in either sequence is a node rather than an atomic value. The default implementation of
schemaEquals() is the same as equals(), but subclasses can override this.
|
| signum | | public double signum()(Code) | | Determine whether the value is negative, zero, or positive
-1 if negative, 0 if zero (including negative zero), +1 if positive, NaN if NaN |
