. Is this a 'fast' way to do this operation? My code spends 90% of the time performing this operation. I'm hoping there is a faster way. Any comments are apprectiate. Thanks! Mark 'To type cast in VB you need to use the API to copy the contents of one dat As far as floating point arithmetic is concerned, you have to design your own architecture with compliance to IEEE 754 standard as mentioned earlier. Just take care of exponent, mantissa, sign bit.

IEEE 754 single precision binary floating-point format: binary32 The IEEE 754 standard specifies a binary32 as having We can now decode the significand by adding the values represented by these bits. Decoded significand: 1 + 0.5 + 0.0625 = 1.5625 = C80000/223 Then we need to multiply with the base, 2, to the power of the exponent to get the final result 1.5625 × 24 = 25 Thus 41c8 0000. From the profiled results of MP3 algorithm on ARM processors it has been observed that, the synthesis filter bank in the audio decoder consumes maximum power. Hence to reduce the power consumption of the filter bank, we developed an IEEE 754 single precision floating-point runtime re-configurable architecture. The proposed architecture consumes less power at run time as the last 12 bits of the.

IEEE 754 single-precision has a precision of 24 bits. So all not-too-small, not-too-large IBM single-precision values can be translated to IEEE 754 single-precision values with no loss of precision. However, the IBM single precision range is larger than the corresponding IEEE 754 range, so extreme IBM single-precision values may overflow to infinity, underflow to zero, or be rounded to a. IEEE 754 format is used to write floating point numbers to the stream, Instead, the encoder (the sender) and the decoder (the receiver) share an implicit understanding, called a Context, which includes the necessary metadata, including the user type definitions. The binary format for a User Type is very similar to that of a Sparse Array; conceptually, a User Type can be considered a Sparse. This post implements a previous post that explains how to convert 32-bit floating point numbers to binary numbers in the IEEE 754 format. What we have is some C++ / Java / Python routines that will allows us to convert a floating point value into it's equivalent binary counterpart, using the standard IEEE 754 representation consisting of the sign bit, exponent and mantissa (fractional part)

The IEEE-754-2008 Packed Decimal Encoding (= PDE) is a way of encoding decimal numbers. Its preliminary version was named IEEE-754r. This method is intended to squeeze out (nearly) all unused space in the set of available bit-patterns. Ordinarily this waste occurs when decimal digits are stored. The PDE-method relies heavily on a method for compressing decimals called Densely Packed Decimal. It will convert a decimal number to its nearest single-precision and double-precision IEEE 754 binary floating-point number, using round-half-to-even rounding (the default IEEE rounding mode). It is implemented with arbitrary-precision arithmetic, so its conversions are correctly rounded. It will convert both normal and subnormal numbers, and will convert numbers that overflow (to infinity) or.

The IEEE specification allows for multiple NaN variants; however, the encoders/decoders may not preserve the distinction. Encoders shall encode a NaN value as an IEEE quiet-NAN (000000000000F8FF) or (0000C0FF). Any unsupported types such as denormalized numbers shall also be encoded as an IEEE quiet-NAN. Any test for equality between NaN values. Decoding scheme of numeric data types (BIGINT, INTEGER, SMALLINT, TINYINT, DOUBLE) is straightforward. A sequence of bytes is read from input message and decoded according to either: big-endian encoding (for integer types) IEEE 754 format for (for DOUBLE).
