| const TInt | KRealFormatTypesMask |
A mask for the set of flags that govern the general format of the character representation of a real number.
These are the flags with symbols starting KRealFormat...
| const TInt | KRealFormatFixed |
Defines the general format of the character representation of a real number. The TRealFormat::iType data member is set to one of these.
The real number is converted to fixed format which has the general pattern: "nnn.ddd", where nnn is the integer portion and ddd is the decimal portion. A negative value is prefixed by a minus sign.
The number of decimal places generated is defined by the value of TRealFormat::iPlaces. Trailing zeroes are generated as required. If necessary, the decimal portion is rounded to fit the specification. If this value is zero, no decimal point and no decimal portion is generated.
Triad separation is available, defined by TRealFormat::iTriad and TRealFormat::iTriLen.
Note that a zero value is converted either to the form "0.000..." with iPlaces '0' characters after the decimal point, if iPlaces is greater than zero, or to "0" if iPlaces is zero.
| const TInt | KRealFormatExponent |
Defines the general format of the character representation of a real number. The TRealFormat::iType data member is set to one of these.
The real number is converted to scientific format with one non-zero digit before the decimal point and a number of digits after the decimal point. Hence the number has the general pattern: "n.dddE+ee" or "n.dddE-ee", or "n.dddE+eee" or "n.dddE-eee".
The decimal portion is followed by the character 'E', a sign ('+' or '-') and the exponent as two digits, including leading zeroes, if necessary. If necessary, the decimal portion is rounded.
A negative value is prefixed by a minus sign.
If the flag KUseSigFigs is not set, TRealFormat::iPlaces defines the number of digits which follow the decimal point. If the flag KUseSigFigs is set, iPlaces defines the maximum number of significant digits to be generated.
Note that, by default, exponents are limited to two digits. Those numbers that require three digits must have the flag KAllowThreeDigitExp set. If iPlaces is zero, the value is rounded to one digit of precision and no decimal point is included.
Triad separation is not available.
Note that a zero value is converted either to the form "0.000...E+00" with iPlaces '0' characters after the decimal point, if iPlaces is greater than zero, or to "0E+00" if iPlaces is zero.
| const TInt | KRealFormatGeneral |
Defines the general format of the character representation of a real number. The TRealFormat::iType data member is set to one of these.
The real number is converted either to fixed or scientific format. The format chosen is the one which can present the greater number of significant digits. Where both formats can present the same number of significant digits, fixed format is used.
The number of decimal places generated depends only on the value of TRealFormat::iWidth; the value of the iPlaces member is ignored.
Trailing zeroes in the decimal portion are discarded.
Triad separation is not available.
Note that a zero value is converted to "0".
| const TInt | KRealFormatNoExponent |
Defines the general format of the character representation of a real number. The TRealFormat::iType data member is set to one of these.
The same as KRealFormatFixed but the TRealFormat::iPlaces is interpreted as specifying the maximum number of significant digits.
Trailing zeroes in the decimal portion are discarded.
| const TInt | KRealFormatCalculator |
Defines the general format of the character representation of a real number. The TRealFormat::iType data member is set to one of these.
The same as KRealFormatGeneral but TRealFormat::iPlaces is interpreted as specifying the maximum number of significant digits, and the number is displayed without an exponent whenever possible.
Trailing zeroes in the decimal portion are discarded.
| const TInt | KRealFormatTypeFlagsMask |
A bitmask for all flags except those with symbols starting KRealFormat...
| const TInt | KExtraSpaceForSign |
A flag that modifies the format of the character representation of a real number.
It reduces the effective width by one character. This forces a large enough value for TRealFormat::iWidth to be chosen to guarantee that positive and negative numbers can be shown to the same precision.
It applies when TRealFormat::iType is set to KRealFormatFixed or KRealFormatGeneral, and should be ORed into TRealFormat::iType after one of these types has been set.
| const TInt | KAllowThreeDigitExp |
A flag that modifies the format of the character representation of a real number.
It allows an exponent to be formatted whose magnitude is greater than 100. If this flag is not set, an attempt to format such a number fails.
If set, three digit exponents are allowed. If not set, only two digit exponents are allowed.
Applies when TRealFormat::iType is set to KRealFormatExponent or KRealFormatGeneral, and should be ORed into TRealFormat::iType after one of these types has been set.
| const TInt | KUseSigFigs |
A flag that modifies the format of the character representation of a real number.
If set, the TRealFormat::iPlaces member is interpreted as the maximum number of significant digits to be generated.
Applies when TRealFormat::iType is set to KRealFormatExponent, and should be ORed into TRealFormat::iType after this type has been set.
| const TInt | KDoNotUseTriads |
A flag that modifies the format of the character representation of a real number.
It disables triad separation.
Applies when TRealFormat::iType is set to KRealFormatFixed or KRealFormatNoExponent, and should be ORed into TRealFormat::iType after one of these types has been set.
| const TInt | KGeneralLimit |
A flag that modifies the format of the character representation of a real number.
If set, this flag limits the precision to KPrecisionLimit digits. If not set, the precision defaults to KMaxPrecision digits.
This flag should be ORed into TRealFormat::iType.
| const TInt | KRealInjectiveLimit |
A flag that modifies the format of the character representation of a real number.
If set, this flag allows enough digits of precision such that the mapping from numeric to string form is injective. For a TReal (=double) input argument this means KIEEEDoubleInjectivePrecision digits. This flag overrides the KGeneralLimit flag if both are set.
This flag should be ORed into TRealFormat::iType.
