gnu.math.ExponentialFormat
| ExponentialFormat | | public class ExponentialFormat extends java.text.Format (Code) | | 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.

| Field Summary | |
| final static double | LOG10
| | public int | expDigits
Number of digits to show in the exponent.
Zero means unspecified - show as many as needed. | | public char | exponentChar
| | public boolean | exponentShowSign
Display sign of exponent even when it is non-negative. | | public int | fracDigits
Number of fractional digits to show.
This is `d' in the CommonLisp spec. | | public boolean | general
| | 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. | | public char | overflowChar
| | public char | padChar
| | public boolean | showPlus
True if '+' should be printed for non-negative number. | | public int | width
