STRING expressions return text strings. They are used to manipulate non-numeric data. The STRING FORMAT expression returns the value from its sub-expression, converted to a floating-point number, and formatted as specified.

The sub-expression may be a PROPERTY, STRING or FLOAT expression. A PRECISION expression node sets the number of significant digits to include, and a SHOW_SIGN expression node sets whether or not to show the sign of the number.

See the EXPRESSION element for DTD and attribute information.
