| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
This constant has the value of IEEE negative double-float infinity. It is a legal floating-point value. In arithmetic operations, it produces double-float infinities of appropriate sign or NaNs, but a finite number (in fact zero) only when divided into a finite number. See the linked discussion for more details.
Infinities like this one can result from normal arithmetic operations,
such as a division by zero in a function with types declared and
compiled so comp:trust-declarations-switch
is true,
but that same call run interpreted may instead signal an error.
See Floating-point infinities and NaNs, and
floating-point underflow and overflow in
implementation.htm. Also see
