decimal data type
The xs:decimal data type represents a subset of the real numbers that can be represented by decimal numerals. Derived from data type xdt:anyAtomicType.
The lexical form of xs:decimal is a finite-length sequence
of decimal digits that are separated by a period as a decimal indicator.
An optional leading sign is allowed. If the sign is omitted, a positive
sign (+) is assumed. Leading and trailing zeros are optional. If the
fractional part is zero, the period and any following zeros can be
omitted. The following numbers are valid examples of this data type:
