Hi Friends

I'm trying to use the double float (15 digit) precision yet cannot even print out such a number correctly....see this attempt (which generates no errors)

pi AS DOUBLE FLOAT
pi=22/7
ans$=str$(pi)
print ans$

Gives "3" !?. Printing 'pi' directly gives the same...

I know, it's been 7 years or so since last playing with DB.

Thanks in advance....

It's because you need .0 at the end of the numbers to make it calculate as a float otherwise it'll treat it as a whole number.

I changed the PI variable in your code to P because PI() is a command in IanMs Matrix 1 Utilities Plugin.

You can also control the number of decimal places:

ans$=str$(p,3)
