 #### Values
 
-Metric values in OpenMetrics MUST be either numbers or complex data types.
-
-Numbers MUST be either floating points or integers. Note that ingestors of the format MAY only support float64. The non-real values NaN, +Inf and -Inf MUST be supported. NaN MUST NOT be considered a missing value, but it MAY be used to signal a division by zero.
-
-Complex data types MUST contain all information necessary to recreate a sample of a Metric Type, with the exception of Start Timestamp and Exemplars.
