## infinity-single*

This constant has the value of IEEE single-float infinity. It is a legal floating-point value. In arithmetic operations, it produces infinities of appropriate sign and format (following standard floating-point coercion rules) 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-double*`, `*negative-infinity-double*`, `*nan-double*`, and `*nan-single*`
