Would syntax for choosing between 64-bit intermediate vs. 32-bit intermediate be appropriate?

  > syntax for choosing between 64-bit intermediate vs. 32-bit intermediate That's exactly what Kahan proposed to be added to Java in the title work ("How Java’s Floating-Point Hurts Everyone Everywhere," which most of the people arguing here didn't digest fully, but I have understanding for that, people who didn't have to do computations don't have enough familiarity with the whole subject), see the page 78: "To fit in with Java’s linguistic proclivities, Borneo allows a programmer to declare a minimum width to which everything narrower is to be widened before Java’s rules are invoked: anonymous float follow Java’s rules ( Borneo’s default; it must match Java’s ) anonymous double widen every narrower operand to double as does K-R C anonymous long double widen every narrower operand to long double ( use on Intel ) anonymous indigenous widen every narrower operand to indigenous. Of course, Java should be repaired promptly to adopt anonymous double as its default, which would then become Borneo’s default too. The scope of an anonymous declaration is a block."
