Value

Value (4 bytes): The 32-bit single precision floating point value as described in [IEEE754].

This structure MUST be interpreted as representing the characters formed by converting the value to base 10. The period "." MUST be used as the decimal point only if a fractional component exists. The least number of digits that exactly reproduces the IEEE representation MUST be used. There MUST NOT be any unnecessary leading or trailing zeroes, except when a decimal point is the first character, in which case a single zero "0" MUST precede the decimal point. Exponential notation MUST be used when the position of the decimal point is outside the range of significant digits. When exponential notation is used, the character "E" MUST be used, and MUST be followed by a plus sign "+" or minus sign "-", and MUST be followed by the magnitude of the exponent.

Furthermore, special values have special characters that MUST be used.
