DIV

Description

The DIV operator is used for integer division. Discards from the division result any fractional part to the right of the decimal point.

If either operand has a non-integer type, the operands are converted to DECIMAL and divided using DECIMAL arithmetic before converting the result to BIGINT. If the result exceeds BIGINT range, an error occurs.

Syntax
