+Floating Point Constant Folding
+
+ Regardless of the type of the operands, floating point
+ constant folding is done in real or greater precision.
+ It is always done following IEEE 754 rules and round-to-nearest
+ is used.
+
+ Floating point constants are internally represented in
+ the implementation in at least real precision, regardless
+ of the constant's type. The extra precision is available for
+ constant folding. Committing to the precision of the result is
+ done as late as possible in the compilation process. For example:
+
+const float f = 0.2f;
+writefln(f - 0.2);
+
+ will print 0. A non-const static variable's value cannot be
+ propagated at compile time, so:
+
+static float f = 0.2f;
+writefln(f - 0.2);
+
+ will print 2.98023e-09. Hex floating point constants can also
+ be used when specific floating point bit patterns are needed that
+ are unaffected by rounding. To find the hex value of 0.2f:
+
+import std.stdio;
+
+void main()
+{
+ writefln("%a", 0.2f);
+}
+
+ which is 0x1.99999ap-3. Using the hex constant:
+
+const float f = 0x1.99999ap-3f;
+writefln(f - 0.2);
+
+
+ prints 2.98023e-09.
+
+ Different compiler settings, optimization settings,
+ and inlining settings can affect opportunities for constant
+ folding, therefore the results of floating point calculations may differ
+ depending on those settings.
+
