Inf

Infinity

Syntax

• inf
  

Description

Inf returns the IEEE arithmetic representation for positive infinity. Infinity results from operations like division by zero and overflow, which lead to results too large to represent as conventional floating-point values.

Examples

1/0, 1.e1000, 2^1000, and exp(1000) all produce Inf.

log(0) produces -Inf.

Inf-Inf and Inf/Inf both produce NaN (Not-a-Number).
