In Oracle, the LOG() function returns the logarithm, base n2, of n1, where n2 is the first argument and n1 is the second.
numeric functions
LN() Function in Oracle
In Oracle, the LN() function returns the natural logarithm of its argument, where the argument is greater than 0.
In other words, it returns the base-e logarithm of its argument.
The number e, also known as Euler’s number, is a mathematical constant approximately equal to 2.71828.
ATAN2() Function in Oracle
In Oracle, the ATAN2() function returns the arctangent (inverse tangent) of its two arguments.
ATAN() Function in Oracle
In Oracle, the ATAN() function returns the arctangent (inverse tangent) of its argument.
In other words, it returns the value whose tangent is the argument.
BITAND() Function in Oracle
In Oracle, the BITAND() function returns a bitwise AND of its two arguments.
ASIN() Function in Oracle
In Oracle, the ASIN() function returns the arcsine (inverse sine) of its argument.
In other words, it returns the value whose sine is the argument.
ACOS() Function in Oracle
In Oracle, the ACOS() function returns the arccosine (inverse cosine) of its argument.
In other words, it returns the value whose cosine is the argument.
ABS() Function in Oracle
In Oracle, the ABS() function returns the absolute value of its argument.
The absolute value is the non-negative value of a real number without regard to its sign. It describes the distance from zero that a number is on the number line, without considering direction.
How OCT() Works in MariaDB
In MariaDB, OCT() is a built-in function that returns a string representation of the octal value of its argument.
How TAN() Works in MariaDB
In MariaDB, TAN() is a built-in numeric function that returns the tangent of its argument.
