The string consists of an arbitrary length decimal numeric string with an optional leading “+” or “–” sign.

Consists of a decimal numeric string with an optional single decimal point and an optional leading “+” or “–” sign. It can optionally have the qualifier vQual:binRep, of type Text, which provides an alternate binary representation for the number when an exact value is needed. The text is interpreted as: std size,endian,hexadecimal_value – std is the standard name ("IEEE754") – size is S for 32-bit and D for 64-bit – endian is L for little-endian, B for big-endian. For example: "IEEE754D,L,3A4901F387D31108" Text A Unicode string.
