I have a problem with an SQL query and i’ve narrowed it down to the following code

SELECT ACOS( (SIN(PI()* 52.9519918465976/180)*SIN(PI()* 52.9519918465976/180))+(COS(PI()*   52.9519918465976/180)*cos(PI()* 52.9519918465976/180)*COS(PI()* -1.14304013581239/180-PI()* -1.14304013581239/180))) AS test

I get the following error message ‘An invalid floating point operation occurred’

Can abody see what the issue is?

Thanks in advance

    Your result in ACOS() is bigger than 1 which can’t be.

    That is because of floating point inaccuracy. it could be 1.00000001 for instance. Putting it just a little below 1 works like this:

    SELECT ACOS( 
             (SIN(PI()* 52.9519918465976/180.0)* SIN(PI()* 52.9519918465976/180.0))
             + (COS(PI()* 52.9519918465976/180)*cos(PI()* 52.9519918465976/180.0)*COS(PI()* -1.14304013581239/180.0-PI()* -1.14304013581239/180.0)) 
             - 0.0000001
           )
