Returns the sample value of a single-element instant vector as a scalar. If the input vector does not have exactly one element, scalar returns NaN.

Return type

scalar

Parameters

v (instant_vector)

Instant vector input.

Example

scalar(sum(http_requests_total))
		

Returns the scalar as a vector with no labels.

Return type

instant_vector

Parameters

s (scalar)

Scalar value.
