REMAINDER

Syntax

Description of the illustration remainder.eps

Purpose

REMAINDER returns the remainder of n2 divided by n1.

This function takes as arguments any numeric data type or any nonnumeric data type that can be implicitly converted to a numeric data type. Oracle determines the argument with the highest numeric precedence, implicitly converts the remaining arguments to that data type, and returns that data type.

The MOD function is similar to REMAINDER except that it uses FLOOR in its formula, whereas REMAINDER uses ROUND. Refer to MOD.

• If n1 = 0 or n2 = infinity, then Oracle returns

  • An error if the arguments are of type NUMBER

  • NaN if the arguments are BINARY_FLOAT or BINARY_DOUBLE.

• If n1 != 0, then the remainder is n2 - (n1*N) where N is the integer nearest n2/n1. If n2/n1 equals x.5, then N is the nearest even integer.

• If n2 is a floating-point number, and if the remainder is 0, then the sign of the remainder is the sign of n2. Remainders of 0 are unsigned for NUMBER values.

Examples

Using table float_point_demo, created for the TO_BINARY_DOUBLE "Examples", the following example divides two floating-point numbers and returns the remainder of that operation:

SELECT bin_float, bin_double, REMAINDER(bin_float, bin_double)
  FROM float_point_demo;

 BIN_FLOAT BIN_DOUBLE REMAINDER(BIN_FLOAT,BIN_DOUBLE)
