Method Details

xsdParseDouble

public static double xsdParseDouble(String lexicalForm)

Parse an XSD double lexical form. Adds in the cases not covered by Double.parseDouble(java.lang.String). INF is strictly upper case, but we accept lower case. -NaN and +NaN are not accepted.

xsdParseFloat

public static float xsdParseFloat(String lexicalForm)

Parse an XSD float lexical form. Adds in the cases not covered by Float.parseFloat(java.lang.String). INF is strictly upper case, but we accept lower case. -NaN and +NaN are not accepted.

xsdParseDecimal

public static BigDecimal xsdParseDecimal(String lexicalForm)

Parse an XSD decimal.

stringForm

public static String stringForm(BigDecimal decimal)

Produce a lexical form for BigDecimal that is compatible with Turtle syntax (i.e it has a decimal point).

stringForm

public static String stringForm(double d)

stringForm

public static String stringForm(float f)

stringFormatARQ

public static String stringFormatARQ(BigDecimal bd)

The format of xsd:decimal used in ARQ expression evaluation. This is XSD 1.0 for long-term consistency (integer values for xsd:decimal have ".0").

stringFormatXSD10

public static String stringFormatXSD10(BigDecimal bd)

Strict XSD 1.0 format for xsd:decimal.

stringFormatXSD11

public static String stringFormatXSD11(BigDecimal bd)

Strict XSD 1.1 format for xsd:decimal.

canonicalDecimalStrNoIntegerDot

public static String canonicalDecimalStrNoIntegerDot(BigDecimal bd)

Decimal format, cast-to-string.

Decimal canonical form where integer values have no ".0" (as in XSD 1.1).

In XSD 1.1, canonical integer-valued decimal has a trailing ".0". In F&O v 3.1, xs:string cast of a decimal which is integer valued, does not have the trailing ".0".

canonicalDecimalStrWithDot

public static String canonicalDecimalStrWithDot(BigDecimal decimal)

Integer-valued decimals have a trailing ".0". (In XML Schema Datatype 1.1 they did not have a ".0".)
