(FLOAT(arg))
Converts a number with a TEXT, INTEGER, or CURRENCY data type to a value with a REAL or DOUBLE data type. This is not the same as the FLOAT data type.
In the following example, the value of vfloat1 is 2., a number that has a REAL data type, and the value of vfloat2 is also 2., a number that has a DOUBLE data type. If a variable is not assigned a data type, it becomes DOUBLE.
SET VAR vfloat1 REAL = (FLOAT(2))
SET VAR vfloat2 = (FLOAT(2))
