Inheritance diagram for DGDouble:
Static Public Member Functions | |
static double | parse (char[] src, uint *ate=null) |
static int | format (double i, inout Style style) |
static char[] | format (char[] dst, double x, uint decimals=6, bool scientific=false, uint mode=3) |
Private Types | |
enum | Flags { Fill = 1, Left = Fill << 1, Prec = Left << 1, Hash = Prec << 1, Space = Hash << 1, Zero = Space << 1, Sign = Zero << 1, Comma = Sign << 1, Plus = Comma << 1, Array = Plus << 1 } |
Static Private Member Functions | |
static void | error (char[] msg) |
Note that this class requires the attendent file dtoa.c be compiled and linked to the application.
While these functions are all static, they are encapsulated within a class inheritance to preserve some namespace cohesion. One might use structs for encapsualtion instead, but then inheritance would be lost. Note that the root class, Styled, is abstract to prevent accidental instantiation of these classes.

Convert a floating-point number to a string. Parameter 'mode' should be specified thusly: 0 ==> shortest string that yields d when read in and rounded to nearest. 1 ==> like 0, but with Steele & White stopping rule; e.g. with IEEE P754 arithmetic , mode 0 gives 1e23 whereas mode 1 gives 9.999999999999999e22. 2 ==> max(1,ndigits) significant digits. This gives a return value similar to that of ecvt, except that trailing zeros are suppressed. 3 ==> through ndigits past the decimal point. This gives a return value similar to that from fcvt, except that trailing zeros are suppressed, and ndigits can be negative. 4,5 ==> similar to 2 and 3, respectively, but (in round-nearest mode) with the tests of mode 0 to possibly return a shorter string that rounds to d. With IEEE arithmetic and compilation with -DHonor_FLT_ROUNDS, modes 4 and 5 behave the same as modes 2 and 3 when FLT_ROUNDS != 1. 6-9 ==> Debugging modes similar to mode - 4: don't try fast floating-point estimate (if applicable).
