Can a floating point number be negative
In computing, floating-point arithmetic (FP) is arithmetic that represents real numbers approximately, using an integer with a fixed precision, called the significand, scaled by an integer exponent of a fixed base. For example, 12.345 can be represented as a base-ten floating-point number: In practice, … See more Floating-point numbers A number representation specifies some way of encoding a number, usually as a string of digits. There are several mechanisms by which strings of digits can … See more The IEEE standardized the computer representation for binary floating-point numbers in IEEE 754 (a.k.a. IEC 60559) in 1985. This first standard is followed by almost all modern machines. It was revised in 2008. IBM mainframes support IBM's own hexadecimal floating point format See more By their nature, all numbers expressed in floating-point format are rational numbers with a terminating expansion in the relevant base (for example, a terminating decimal expansion … See more Floating-point computation in a computer can run into three kinds of problems: • An operation can be mathematically undefined, such as ∞/∞, or division by zero. • An operation can be legal in principle, but not supported by the specific format, for example, … See more A floating-point number consists of two fixed-point components, whose range depends exclusively on the number of bits or digits in their representation.
