This means they return the same results each time they are called with a specific set of input values. RAND is deterministic only when a seed parameter is specified. For more information about function determinism, see Deterministic and Nondeterministic Functions....
A mathematical function performs a mathematical operation on numeric expressions and returns the result of the operation.By default, a number passed to a mathematical function will be interpreted as a double precision floating point number.See Also...
select abs(122320837456298376592387456923748); -- Calculate the absolute value of the id field in tbl1. The following example shows the usage of an ABS function in SQL statements. Other built-in functions, except window functions and aggregate functions, are used in a similar way. select abs(...

mysql> SELECT ABS(2); -> 2 mysql> SELECT ABS(-32); -> 32 This function is safe to use with BIGINT values. ACOS(X) Returns the arc cosine of X, that is, the value whose cosine is X. Returns NULL if X is not in the range -1 to 1. mysql> SELECT ACOS(1); -> 0 my...
The factorial of 0 is 1. Likewise, the factorial() function returns 1 for any negative value. The maximum positive value for the input argument is 20, a value of 21 or greater will cause exception throw. Syntax factorial(n)Example SELECT factorial(10);Result: ...
Some of these functions are provided in multiple forms with different argument types. Except where noted, any given form of a function returns the same data type as its argument. The functions working with DOUBLE PRECISION data could vary in accuracy and behavior in boundary cases depending on ...
