| Language basics / Data types | |
The FLOAT data type stores values as double-precision floating-point binary numbers with up to 16 significant digits.
FLOAT [(precision)]
The storage of FLOAT variables is based on 8 bytes of signed data ( =64 bits), this type is equivalent to the double data type in C.
FLOAT variables are initialized to zero in functions, modules and globals.
FLOAT values can be converted to strings according to the DBMONEY environment variable (defines the decimal separator).
This data type it is not recommended for exact decimal storage; use the DECIMAL type instead.
