How does MOD function work in SQL?
MOD() Function in MySQL. The MOD() function in MySQL is used to find the remainder of one number divided by another. The MOD() function returns the remainder of dividend divided by divisor. if the divisor is zero, it returns NULL.
Can you use modulus in SQL?
You can use the modulo arithmetic operator in the select list of the SELECT statement with any combination of column names, numeric constants, or any valid expression of the integer and monetary data type categories or the numeric data type.
How do you write a MOD function?
b = mod( a , m ) returns the remainder after division of a by m , where a is the dividend and m is the divisor. This function is often called the modulo operation, which can be expressed as b = a – m. *floor(a./m) . The mod function follows the convention that mod(a,0) returns a .
What is MOD syntax?
This article describes the formula syntax and usage of the MOD function in Microsoft Excel.
|=MOD(-3, 2)||Remainder of -3/2. The sign is the same as divisor||1|
|=MOD(3, -2)||Remainder of 3/-2. The sign is the same as divisor||-1|
What is mod in Oracle SQL?
Description. The Oracle MOD() is used to return the remainder of a dividend divided by a divisor. This function also works on fractional values and returns the exact remainder. The function returns dividend when the value of divisor is 0.
How does MOD function work?
The MOD function returns the remainder after division. For example, MOD(3,2) returns 1, because 2 goes into 3 once, with a remainder of 1. The MOD function takes two arguments: number and divisor. Number is the number to be divided, and divisor is the number used to divide.
What is ABS function in SQL?
A mathematical function that returns the absolute (positive) value of the specified numeric expression. ( ABS changes negative values to positive values. ABS has no effect on zero or positive values.) Transact-SQL Syntax Conventions.
How do you find odd and even rows in SQL?
Write a subquery with an ORDER BY clause. Along with the data columns, select the pseudocolumn rownum with an alias, say rn. In the outer query, reference the alias rn and use the mod function to get odd rows or even rows.
How do you get a mod number?
Modulus on a Standard Calculator
- Divide a by n.
- Subtract the whole part of the resulting quantity.
- Multiply by n to obtain the modulus.
What is the mod symbol?
Modulo is a math operation that finds the remainder when one integer is divided by another. In writing, it is frequently abbreviated as mod, or represented by the symbol %.
How do you use mod codes?
The modulus operator returns the remainder of a division of one number by another. In most programming languages, modulo is indicated with a percent sign. For example, “4 mod 2” or “4%2” returns 0, because 2 divides into 4 perfectly, without a remainder.
How do I use Visual Basic mods?
Mod in VB.NET is the Modulo operation. It returns the remainder when one number is divided by another. For example, if you divided 4 by 2, your mod result would be 0 (no remainder). If you divided 5 by 2, your mod result would be 1.
What does MOD and DIV mean?
You may be unfamiliar with the following operators: … DIV returns a whole number result (or quotient) of a division, which means that the fractional part of the result is dismissed. MOD returns the remainder of a division. round( ) rounds up the result of an operation.
What types does the MOD (%) work on?
3) modulus operator is not just applicable to integral types e.g. byte, short, int, long but also to floating-point types like float and double. 4) You can also use the remainder operator to check if a number is even or odd, or if a year is leap year.
