In iotdb-engine.properties, there are two configs that control the infer type of a string.
// register time series as which type when receiving an integer string "67"
integer_string_infer_type=FLOAT
// register time series as which type when receiving a floating number string "6.7"
floating_string_infer_type=FLOAT
Before inter type, we first classify the numeric string as integer_string or floating_string.
For Scientific notation, we should classify 1.34464E3 as floating_string and 1.34464E7 as integer_string.
