*infinity-double*

This constant has the value of IEEE 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 *negative-infinity-single*, *infinity-single*, *negative-infinity-double*, *nan-double*, and *nan-single*
