Detailed Description

BER object to handle float.

IEEE 754 single precision 32-bit is used to represent float.

• Type is TYPE_OPAQUEFLOAT.
• Length is fixed, 4 bytes, short form encoding.
• Size is fixed, 7 bytes.

Example

OpaqueFLoat	Encoding
25.589001	9f 78 04 41 CC B6 46

Note

OpaqueFloatBER is never used alone but always embedded in an OpaqueBER.
