Returns the numeric representation of ∞, positive infinity.
INF
A real representing positive infinity.
exp(1000)
returns inf
1/inf
returns 0.0
The configuration parameter DEFAULT_MATH_VALUE determines the result of expressions such as 1/0. DEFAULT_MATH_VALUE defaults to 0.0, but can be set to inf.
If the configuration parameter USE_DEFAULT_MATH_MATH is 0, DEFAULT_MATH_VALUE is ignored and expressions such as 1/0 result in the system default.
Overflow operations return INF as a result.
