Fixed point types
WebJul 14, 2024 · 3. There are no fixed and ufixed data types in Solidity. Data types in Solidity are categorised into Value types and Reference types. Value types includes bool, int, uint, byte, etc. byte is a fixed-sized byte array. Reference types includes Arrays, Structs, Mappings. To know about these in detail, please go through this Solidity Types ... Fixed-point programming normally requires the use of integer types of different widths. Fixed-point applications can make use of block floating point , which is a fixed-point environment having each array (block) of fixed-point data be scaled with a common exponent in a single word. 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 A common use of decimal fixed-point is for storing monetary values, for which the complicated rounding rules of floating-point numbers are … 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 as the integer value 1230 with implicit scaling factor of 1/1000 (meaning that the … 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 their common implicit scaling factor, can thus can be stored in the same program … 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
