- All Implemented Interfaces:
Serializable
,Cloneable
public class ExponentialFormat extends Format
Format a real number using a floating-point format. However, if `general' is true, and the number "fits", use a fixed-point format (like printf %g). Used for Common Lisp specs ~E and ~G; also C-style %e and %g.- See Also:

Field Detail
-
fracDigits
public int fracDigits
Number of fractional digits to show. This is `d' in the CommonLisp spec.
-
intDigits
public int intDigits
Number of digits to show in the integer part of the result. If positive, The number of digits before the decimal point. If negative, the -intDigits zeros are emitted after the decimal point. This is `k' in the CommonLisp spec.
-
expDigits
public int expDigits
Number of digits to show in the exponent. Zero means unspecified - show as many as needed.
