Deserialize any JSON value. Allows atomic values on the top level

Like decodeV, but returns an error message when decoding fails.

Convert a RealFloat (like a Double or Float) into a Scientific number.

Note that this function uses floatToDigits to compute the digits and exponent of the RealFloat number. Be aware that the algorithm used in floatToDigits doesn't work as expected for some numbers, e.g. as the Double 1e23 is converted to 9.9999999999999991611392e22, and that value is shown as 9.999999999999999e22 rather than the shorter 1e23; the algorithm doesn't take the rounding direction for values exactly half-way between two adjacent representable values into account, so if you have a value with a short decimal representation exactly half-way between two adjacent representable values, like 5^23*2^e for e close to 23, the algorithm doesn't know in which direction the short decimal representation would be rounded and computes more digits

Optionally create a Pair.

Convert a Scientific into an Integer if it doesn't have decimal points, otherwise to a Double.

floatingOrInteger determines if the scientific is floating point or integer. In case it's floating-point the scientific is converted to the desired RealFloat using toRealFloat.
