What is a key feature of the IEEE-754r standard?
Focus on decimal floating-point representation
What is the main reason for the extension of the standard to include decimal floating-point representation?
Binary floating-point cannot represent decimal fractions exactly.
Which of the following is a characteristic of the new 128-bit 'quad-precision' format described in the text?
It is an addition to existing binary formats.
What do the three new decimal formats introduced in the text match in terms of lengths?
They match the lengths of binary formats.
In order to achieve maximum range and precision in decimal floating-point representation, what does the text suggest merging?
Part of the exponent and part of the mantissa into a combination field.
What was the main objective of the IEEE-854 standard mentioned in the text?
To establish a standard without radix and word length dependencies.
Why was it necessary to revise and rewrite many definitions during the revision process mentioned in the text?
For clarification and consistency.
Test your knowledge on the characteristic parameters of IEEE-754 formats, including precision levels for Single, Single-extended, Double, and Double-extended formats. Questions cover the number of bits for sign, exponent, mantissa, total length, and decimal digits of precision.
