[Bug classpath/39743] New: BigDecimal fails on lots of tests |

Hi,
I found a test suite for BigDecimal on Internet and adapted it to run with
classpath's BigDecimal. First i ran the tests over Java's BigDecimal, removed
all tests that failed. Then i used BigDecimal from version 0.98. Several tests
had failed. I made some fixes, which i describe below, but most are broken.
First, my fixes:
public BigInteger(String s, int radix)
...
char ch = len == 0 ? 0 : s.charAt(0); // guich: test if len is 0
public BigDecimal(String num)
replace:
scale -= Convert.toInt(num.substring(point));
by:
if (dot >= 0) // guich: no dot, have to add, not sub
scale -= Convert.toInt(num.substring(point));
else
scale += Convert.toInt(num.substring(point));
public String toString()
replace:
if (point - 1 >= 0)
val.append('+');
val.append(point - 1);
to
// guich: 1E+9 was translating to 1E-9
if (scale >= 0) val.append('+');
val.append(scale);
I can't find how to attach the testcases, so i posted to a url:
www.totalcross.com/TCTestWin.java
The commented out tests run with java.math.BigDecimal/BigInteger, but fail on
classpath's.
