Just as in IEEE 754, positive and negative infinity are represented with their corresponding sign bits, all 8 exponent bits set (FF hex) and all significand bits zero. Explicitly, Explicitly, val s_exponent_signcnd +inf = 0_11111111_0000000 -inf = 1_11111111_0000000
An infinity or maximal finite value is returned, depending on which rounding is used. divide-by-zero, set if the result is infinite given finite operands, returning an infinity, either +∞ or −∞. invalid, set if a finite or infinite result cannot be returned e.g. sqrt(−1) or 0/0, returning a quiet NaN.
For integers, the term "integer underflow" typically refers to a special kind of integer overflow or integer wraparound condition whereby the result of subtraction would result in a value less than the minimum allowed for a given integer type, i.e. the ideal result was closer to negative infinity than the output type's representable value ...
The first four partial sums of 1 + 2 + 4 + 8 + ⋯. In mathematics, 1 + 2 + 4 + 8 + ⋯ is the infinite series whose terms are the successive powers of two. As a geometric series, it is characterized by its first term, 1, and its common ratio, 2. As a series of real numbers it diverges to infinity, so the sum of this series is infinity.
The positive and negative normalized numbers closest to zero (represented with the binary value 1 in the Exp field and 0 in the fraction field) are ±1 × 2 −1022 ≈ ±2.22507 × 10 −308; The finite positive and finite negative numbers furthest from zero (represented by the value with 2046 in the Exp field and all 1s in the fraction field) are
For instance, 1/(−0) returns negative infinity, while 1/(+0) returns positive infinity (so that the identity 1/(1/±∞) = ±∞ is maintained). Other common functions with a discontinuity at x=0 which might treat +0 and −0 differently include Γ (x) and the principal square root of y + xi for any negative number y. As with any ...
Analytic continuation around the pole at s = 1 leads to a region of negative values, including ζ(−1) = − + 1 / 12 . In zeta function regularization, the series = is replaced by the series =. The latter series is an example of a Dirichlet series.
In mathematical analysis, limit superior and limit inferior are important tools for studying sequences of real numbers.Since the supremum and infimum of an unbounded set of real numbers may not exist (the reals are not a complete lattice), it is convenient to consider sequences in the affinely extended real number system: we add the positive and negative infinities to the real line to give the ...
