Buffer#writeFloat/writeDouble methods don't return an error code yet while the others do #18115

• Version: 9.4.0
• Platform: Windows 10 64-bit
• Subsystem: buffer.js

Note how the first error has the ERR_INDEX_OUT_OF_RANGE code while the second one doesn't.

$ node
> var b = new Buffer([])
undefined
> b.writeInt8(3)
RangeError [ERR_INDEX_OUT_OF_RANGE]: Index out of range
    at checkInt (buffer.js:1277:11)
    at Buffer.writeInt8 (buffer.js:1442:5)
> b.writeDoubleBE(3)
RangeError: Index out of range
    at Buffer.writeDoubleBE (buffer.js:1533:5)
>

The affected methods are the write float/double LE/BE functions. All others behave correctly.

This complicates error handling unnecessarily and I don't think this is intended behavior. Bug?
