canonicalDecimalStrNoIntegerDot

@Deprecated(forRemoval=true)
public static String canonicalDecimalStrNoIntegerDot(BigDecimal bd)

Deprecated, for removal: This API element is subject to removal in a future version.

Use XSDNumUtils.stringFormatXSD11(java.math.BigDecimal) instead

Decimal format, cast-to-string.

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

In XSD 1.0, canonical integer-valued decimal has a trailing ".0". In XSD 1.1 and F&O v 3.1, xs:string cast of a decimal which is integer valued, does not have the trailing ".0".

canonicalDecimalStr

@Deprecated(forRemoval=true)
public static String canonicalDecimalStr(BigDecimal decimal)

Deprecated, for removal: This API element is subject to removal in a future version.

Use XSDNumUtils.stringFormatXSD10(BigDecimal) instead

Canonical decimal according to XML Schema Datatype 2 v1.0. Integer-valued decimals have a trailing ".0". (In XML Schema Datatype 1.1 they did not have a ".0".)
