Using count trend in grpc return floating point

[sakti]

I am trying to visualize the rate of gRPC requests using the count stat function in the K6_PROMETHEUS_RW_TREND_STATS environment variable. However, the result returns a value with a floating point, not an integer.

k6_grpc_req_duration_count{instance_id="1", job_name="grpc-load-test-1", method="SayHello", name="/podinfo.Greeter/SayHello", scenario="default", service="podinfo.Greeter", status="0", testid="push-1", url="target-podinfo-grpc.default.svc.cluster.local:10001/podinfo.Greeter/SayHello"}      24.712

Is this expected?
