New 4D variable data type – float

Now that 4Dv11 SQL supports float data type; it would be nice to match that with a C_FLOAT. Using C_REAL throws an error for incompatible assignment at runtime.

I.e. if your database has a field with float data type don’t plan on using it with native 4D code, and don’t expect the complier to warn you. See my feature request with 4D.

C_REAL($vr_test)
` throws error (from GET LAST ERROR STACK): 54 4DRT Argument types are incompatible.
$vr_test:=[Table]float_field

There is an Is Float constant to compare to GET FIELD PROPERTIES data type return longint.

And while we’re at it, why are SQL data type values different from GET FIELD PROPERTIES data type values.
