[REBOL] How to obtain a 64-bit IEEE754 representation of a decimal number

From: lmecir::mbox::vol::cz at: 2-Feb-2004 13:59

convert: func [
    x
    /local y
] [
    y: make struct! compose/deep [x [(type?/word x)]] reduce [x]
    third y
]

Usage:

    convert 0.2 ; == #{9A9999999999C93F}

this is a big endian form of the number (in Windows). If you prefer a
little endian form, which is more (human) readable, use:

    head reverse convert 0.2 ; == #{3FC999999999999A}
