Purpose
Returns the square root of a number. You can call this function from the MapBasic window in MapInfo Pro.
Syntax
Sqr( num_expr )num_expr is a positive numeric expression.
Return Value
Float
Description
The Sqr() function returns the square root of the numeric expression specified by num_expr. Since the square root operation is undefined for negative real numbers, num_expr should represent a value greater than or equal to zero.
Taking the square root of a number is equivalent to raising that number to the power 0.5. Accordingly, the expression Sqr(n) is equivalent to the expression n ^ 0.5; the Sqr() function, however, provides the fastest calculation of square roots.
