Numeric literals include integers literals and floating-point literals (doubles).
Integers are 64 bit digitals, and can be preceded by + or - to indicate a positive or negative value, respectively. They're the same as
int64_t in the C language.
Notice that the maximum value for the positive integers is
9223372036854775807. It's syntax-error if you try to input any value greater than the maximum. So as the minimum value
-9223372036854775808 for the negative integers.
Floating-Point Literals (Doubles)¶
Floating-points are the same as
double in the
The range for double is about
Scientific notations is not supported yet.
Nebula Graph supports using scientific notation to represent the Double type. For example:
nebula> CREATE TAG test1(price DOUBLE); nebula> INSERT VERTEX test1(price) VALUES 100:(1.2E3);
