float
Example
The following example returns the base-10 logarithm of various float values.
CREATE TABLE [Base-10 Logarithms] ([LOG10 2] float, [LOG10 20] float, [LOG10 200] float);
INSERT INTO [Base-10 Logarithms]
([LOG10 2], [LOG10 20], [LOG10 200])
VALUES (LOG10(2), LOG10(20), LOG10(200));
SELECT [LOG10 2], [LOG10 20], [LOG10 200]
FROM [Base-10 Logarithms];
