Returns the positive square root of the specified value.
SQRT(x)
x is a positive or zero floating-point value.
SQRT(4.0) /* returns 2.0 */
An SQRT operation on floating-point decimal data is actually performed using the floating-point binary operation. Thus, the range of the operands and the result of the operation are limited to the ranges for floating-point binary numbers.
Description
The SORT function returns the positive square root of x. The result has the same data type as x.
