Floating-Point Decimal Literals
Floating-point literals can exactly represent FLOAT, SMALLFLOAT,
and DECIMAL(p) values, using a decimal point or exponential
notation, or both. They can approximately represent real numbers in
exponential notation. The next examples show floating point numbers:
-123.45E6 1.23456E2 123456.0E-3
The E
in the previous examples is the
symbol for exponential notation. The digit that follows E
is
the value of the exponent. For example, the number 3E5 (or 3E+5) means
3 multiplied by 10 to the fifth power, and the number 3E-5 means 3
multiplied by the reciprocal of 10 to the fifth power.
