Operations with BigDecimal and double in Java
bigdecimal, double, java, variables
Solution
Operations are only supported for primitive types (and + for Strings)
BigDecimals has implemented the operations as functions.
you can only uses BigDecimals for operations with BigDecimals. So you need to convert your double value:
BigDecimal result = new BigDecimal(doubleValue).multiply(factor2);
Problem
I am trying to use Advogadro's number (6.022*10^23) in a java program and i use BigDecimal variable to store it. However i want to multiply it with an int or a double and still keep the precision, but it throws an error! ``` bad operand types for binary operator '*' first type: double second type: BigDecimal ``` Is there any simple way to do that? Also is there a way to print the result in scientific notation? Thanks in advance!
