# setFloat64 abstract method

void setFloat64(

1. int byteOffset,
2. double value, [
3. Endian endian = Endian.big

])

Sets the eight bytes starting at the specified `byteOffset` in this object to the IEEE 754 double-precision binary floating-point (binary64) representation of the specified `value`.

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

## Implementation

    void setFloat64(int byteOffset, double value, [Endian endian = Endian.big]);
