//// Functions for working with floats.
////
//// ## Float representation
////
//// Floats are represented as 64 bit floating point numbers on both the Erlang
//// and JavaScript runtimes. The floating point behaviour is native to their
//// respective runtimes, so their exact behaviour will be slightly different on
//// the two runtimes.
////
//// ### Infinity and NaN
////
//// Under the JavaScript runtime, exceeding the maximum (or minimum)
//// representable value for a floating point value will result in Infinity (or
//// -Infinity). Should you try to divide two infinities you will get NaN as a
//// result.
////
//// When running on BEAM, exceeding the maximum (or minimum) representable
//// value for a floating point value will raise an error.
////
//// ## Division by zero
