# getFloat64 abstract method

double getFloat64(

1. int byteOffset, [
2. Endian endian = Endian.big

])

The floating point number represented by the eight bytes at the specified `byteOffset` in this object, in IEEE 754 double-precision binary floating-point format (binary64).

The `byteOffset` must be non-negative, and `byteOffset + 8` must be less than or equal to the length of this object.

## Implementation

    double getFloat64(int byteOffset, [Endian endian = Endian.big]);
