8. Infinity, NaNs, and sign bit 8.0 | |
8.1 Infinity arithmetic | |
Infinity arithmetic shall be construed as the limiting case of real arithmetic with operands of arbitrarily large | |
magnitude, when such a limit exists. Infinities shall be interpreted in the affine sense, that is, –∞< (every finite number) < +∞. | |
Operations on infinite operands are usually exact and therefore signal no exceptions. The exceptions that do | |
pertain to infinities are signaled only when: | |
∞ is an invalid operand (see 9.2), | |
∞ is created from finite operands by overflow (see 9.4) or division by zero (see 9.3), remainder(subnormal, ∞) signals underflow, | |
nextAfter(x, ∞) signals underflow and inexact if the result would be subnormal, |
