Functions

func IsSupportedValue

func IsSupportedValue(value, min, max float64) bool

IsSupportedValue checks to see if the metric is between the min value and 2^360 and not a NaN. This matches the accepted range described in the MetricDatum documentation https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_MetricDatum.html
