Use of BigDecimal for huge numbers
Mar 9th, 2007, 2:04pm  
I'm trying to deal with some huge numbers, as the default pow() function returns infinity for a problem I am working on.  

Can you advise where I am going wrong?

---code ---

java.math.BigDecimal pow_huge (int num, int power) {
 
 java.math.BigDecimal d_num = new java.math.BigDecimal(num);
 
 return d_num.pow(power); // << line 181

}


--- error ---

/tmp/build34005.tmp/Temporary_629_8642.java:181:10:181:25: Semantic Error: No accessible method with signature "pow(int)" was found in type "java.math.BigDecimal".

BigDecimal.pow(int) was introduced in Java 1.5.  (You can tell by looking at the "Since:" value in the javadoc.)
