!1 Evaluator of expressions: $!--!{= =}
!2 Syntax
'''{{{ $!--!{= [format:] expression =} }}}'''
!3 Expression
An expression may be a combination of constants, variables, and opertors. All internal calculations use the Java ''double'' numeric type.
!3 Format
A format is a specifier that describes the rendering of the numeric result. The format specifier is described by the Java 5 String class's .format() method:
{{{ %[flags][width][.precision]conversion}}} *!note N.B., The ''[argument_index$]'' specifier is not permitted.
Additionally, a formatting locale can be defined by setting the variable ''FORMAT_LOCALE'' to override the default JVM locale.

* [[format string][http://java.sun.com/j2se/1.5.0/docs/api/java/util/Formatter.html#syntax]]
* [[String.format()][http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/String.html#format(java.util.Locale,%20java.lang.String,%20java.lang.Object...)]]
* [[String class][http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html]]
!3 Examples
{{{ $!--!{= 12 + 23 =} renders (sand brackets) as [35]
$!--!{=%5.4f:1.414=} : [1.4140]
$!--!{=%05X:14+14=} : [0001C]
$!--!{= %-10s : 123 =} : [123 ]}}}
And when specifying a formatting locale:
{{{ !define FORMAT_LOCALE {fr}
$!--!{=%5.4f:1.414=} : [1,4140]}}}
