Construct a float
value from an item value.
The following construct(s) refer to this construct:
xs:float(item $value) => float
This is a constructor function that takes an item value as argument and
returns a value of type xs:float
. If the argument is a literal,
then the literal must be a valid lexical form of its type.
As specified in the respective section of the W3C recommendation
XML
Schema Part 2: Datatypes, a value of type xs:float
represents a single-precision floating point number according to IEEE 754-1985.
The lexical form uses scientific notation, consisting of the mantissa which
must be a decimal number, the letter "E" or "e", and an exponent which must be
an integer value.

Generate a valid value of type xs:float
:

This number is represented as 2.00227E3
.
