Scalar. Converts a given value to a floating point value.
value |
The value to convert. A String converts based on the format for a Float literal. An Interval returns a value representing a number of microseconds. A Timestamp returns a value representing the number of microseconds from the epoch (midnight, January 1, 1970 UTC). Timestamps prior to the epoch convert to a negative value. |
The following example takes the integer value of NumContracts, converts it to a Float and then multiplies it by the floating point number 100:
INSERT INTO OutStream SELECT 100.0 * TO_FLOAT(Trades.NumContracts) FROM Trades;
