Among strange results I cannot compute 1/6 with 31 correct digits. Perhaps because using double precision 6* (1/6)=1 exactly although 1/6 = 1.666666666666667e-01!! WebA floating-point (FP) number is a kind of fraction where the radix point is allowed to move. If the radix point is fixed, then those fractional numbers are called fixed-point numbers. The best example of fixed-point numbers are those represented in commerce, finance while that of floating-point is the scientific constants and values.

WebWe present algorithms for accurately converting ﬂoating-point numbers to decimal representation. They are fast (up to 4 times faster than commonly used algorithms that use high-precision in-tegers) and correct: any printed number will evaluate to the same number, when read again. Our algorithms are fast, because they require only ﬁxed-size Web1 day ago · Floating-point numbers are represented in computer hardware as base 2 (binary) fractions. For example, the decimal fraction 0.125 has value 1/10 + 2/100 + 5/1000, and in the same way the binary fraction 0.001 has value 0/2 + 0/4 + 1/8. These two fractions have identical values, the only real difference being that the first is written in base 10 ...
