The single-precision floating-point number mentioned above only uses 32 bits to represent. In order to make the error smaller, IEEE 754 also defines how to use 64-bit to represent floating-point numbers. Compared with 32 bits, the fraction part is more than twice as large. 23 bit becomes ...
It is an object of the invention to specify a method and an apparatus which provides software diversity of the said type for floating point arithmetic; in particular, the aim is for the invention described also to be able to be applied in a real-time environment. The subject matter is a ...
The finite word length used in the computer causes an error in computing the Fourier coefficients. This paper derives explicit expressions for the mean square error in the FFT when floating-point arithmetics are used. Upper and lower bounds for the total relative mean square error are given. ...

The section Relative Error and Ulps describes how it is measured. Since most floating-point calculations have rounding error anyway, does it matter if the basic arithmetic operations introduce a little bit more rounding error than necessary? That question is a main theme throughout this section. ...
Use integral,BCD, orCurrencyvariables to avoid the IEEE floating-point representation error. Understand the Data Flow In Delphi, intermediate results ofSingleprecision floating-point expressions are always implicitly stored asExtendedon x86. By default, all x64 arithmetic operations and expressions involvi...
This chapter makes no attempt to teach or explain numerical error analysis. The material presented here is intended to introduce the IEEE floating-point model as implemented by Fortran 95. 6.2IEEE Floating-Point Arithmetic IEEE arithmetic is a relatively new way of dealing with arithmetic operations...

The need to construct architectures in VLSI has focused attention on unnormalized floating point arithmetic. Certain unnormalized arithmetics allow one to 'pipe on digits,' thus producing significant speed up in computation and making the input problems of special purpose devices such as systolic arrays...
