For example, the open source money management application GnuCash, written in C, switched from floating-point to fixed-point as of version 1.6, for … See more In computing, fixed-point is a method of representing fractional (non-integer) numbers by storing a fixed number of digits of their fractional part. Dollar amounts, for example, are often stored with exactly two fractional digits, … See more Scaling and renormalization Typical processors do not have specific support for fixed-point arithmetic. However, most computers with binary arithmetic have fast See more Decimal fixed point multiplication Suppose there is the following multiplication with 2 fixed point 3 decimal place numbers. See more A fixed-point representation of a fractional number is essentially an integer that is to be implicitly multiplied by a fixed scaling factor. For example, the value 1.23 can be stored in a variable … See more Addition and subtraction To add or subtract two values with the same implicit scaling factor, it is sufficient to add or subtract the underlying integers; the result will have … See more Explicit support for fixed-point numbers is provided by a few computer languages, notably PL/I, COBOL, Ada, JOVIAL, and Coral 66. … See more Various notations have been used to concisely specify the parameters of a fixed-point format.

WebThis is a decimal to binary floating-point converter. 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.
