A Quick Look at EXP() in SQLite
The exp() function in SQLite calculates the exponential of a given number, where the base is the mathematical constant e (approximately 2.71828). In other words, it returns e raised to the power of x for a given input x.
This function can be useful in scientific and statistical calculations involving exponential growth, decay, and other natural logarithmic-based transformations.
Continue readingHow SQLite’s LN() Function Works
In SQLite, the LN() function returns the natural logarithm (logarithm to the base e) of a given positive number.
This function is helpful in mathematical calculations involving growth rates, exponential functions, and natural logarithmic transformations.
Continue readingUnderstanding the total_changes() Function in SQLite
SQLite is a popular, lightweight, SQL-based relational database engine, frequently used in applications where a full database management system isn’t necessary. Among its various features, SQLite offers built-in functions to track the number of changes made to the database during operations, and one of these functions is total_changes().
In this article, we’ll discuss what the total_changes() function does, how it can be used, and provide examples to illustrate its functionality.
A Quick Look at the DEGREES() Function in SQLite
In SQLite, the degrees() function is used to convert an angle from radians to degrees. In trigonometry, angles are commonly measured in either radians or degrees, and this function helps to easily switch from one unit to the other.
How the SIN() Function Works in SQLite
In SQLite, the SIN() function calculates the sine of an angle specified in radians.
This is a fundamental trigonometric function that returns a value between -1 and 1, representing the ratio of the opposite side to the hypotenuse in a right triangle.
Continue readingUnderstanding the LOG2() Function in SQLite
The log2() function in SQLite calculates the base-2 logarithm of a given number.
This function can be useful for scenarios such as binary calculations, information theory, or situations where the base-2 logarithm is needed.
Continue readingA Quick Look TANH() in SQLite
The tanh() function in SQLite calculates the hyperbolic tangent of a number.
The hyperbolic tangent is the ratio of hyperbolic sine to hyperbolic cosine, producing values between -1 and 1.
Continue readingUnderstanding the TRUNC() Function in SQLite
The SQLite TRUNC() function is used to truncate a number to an integer. It returns the integer part of its argument rounding toward zero.
TRUNC()is similar to CEIL() and FLOOR(), except that TRUNC() always rounds toward zero. CEIL() on the other hand, always rounds up, and FLOOR() always rounds down.
Overview of LOG() in SQLite
The LOG() function in SQLite calculates the logarithm of a given number to a specified base, with 10 being the default base.
This is helpful for logarithmic transformations or calculations requiring a specific base (e.g., base 10 for common logarithms or base 2 for binary logarithms).
