How to work with very tiny float numbers without precision loss? Translates a double into a BigDecimal which is the exact decimal representation of the double's binary floating-point value.The scale of the returned BigDecimal is the smallest value such that (10 scale × val) is an integer. But I … A floating-point value that's converted to another floating-point type undergoes no change in value if the original value is representable exactly in the result type. 10/02/2019; 4 minutes to read +1; In this article.
