For more information refer to the Single Structure topic in MSDN.

Definition

A Single value type is defined in the following manner:

[ws][sign][integral-digits[,]]integral-digits[.[fractional-digits]]|.[fractional-digits][e[sign]exponential-digits][ws]
Item Behaviour Description
ws Optional White space.
sign Optional Minus sign indicating a negative Single value.
integral-digits Required if fractional-digits is not present A series of digits ranging from 0 to 9 that specify the integral part of the number. Runs of integral-digits can be partitioned by a group-separator symbol.
, Optional A culture-specific thousands separator symbol.
. Optional A culture-specific decimal point symbol.
fractional-digits Optional A series of digits ranging from 0 to 9 that specify the fractional part of the number.
e Optional Indicates an exponential (scientific) notation.
exponential-digits Optional A series of digits ranging from 0 to 9 that specify an exponent.

Predefined values

The following is a list of predefined Single values:

Default value 0
Minimum value -3.402823e38
Maximum value 3.402823e38

Configuration

A Single attribute value configuration has the following format:

<exampleElement exampleAttribute="123.456" />
