Clarify Float.toInt is truncating

motoko-base/src/Float.mo

Lines 467 to 476 in 2dca37c

	/// Conversion to Int.
	///
	/// Traps for `inf`, `-inf`, and `NaN`.
	///
	/// Example:
	/// ```motoko
	/// import Float "mo:base/Float";
	///
	/// Float.toInt(1.2e6) // => +1_200_000
	/// ```

This doc string should describe the exact behaviour like the doc string for toInt64 does. I believe the behaviour is the same (truncating). Maybe copy the doc string from toInt64 including the example with a negative number.
