Bug: Threshold Casting Issue Affects APDEX Calculation

The apdex and user_misery functions cast the threshold argument to int, but their argument definitions allow "number" types (including floats). This causes float thresholds to be truncated, leading to a loss of precision in calculations.

src/sentry/search/eap/spans/formulas.py#L815-L816

Lines 815 to 816 in 8d5a551

	response_time_field = cast(AttributeKey, args[0])
	threshold = cast(int, args[1])
