numpy.inf

IEEE 754 floating point representation of (positive) infinity.

Returns

yfloat

A floating point representation of positive infinity.

isinf : Shows which elements are positive or negative infinity

isposinf : Shows which elements are positive infinity

isneginf : Shows which elements are negative infinity

isnan : Shows which elements are Not a Number

isfinite : Shows which elements are finite (not one of Not a Number, positive infinity and negative infinity)

Notes

NumPy uses the IEEE Standard for Binary Floating-Point for Arithmetic (IEEE 754). This means that Not a Number is not equivalent to infinity. Also that positive infinity is not equivalent to negative infinity. But infinity is equivalent to positive infinity.

Inf, Infinity, PINF and infty are aliases for inf.

Examples

>>> np.inf
inf
>>> np.array([1]) / 0.
array([ Inf])
