[Java] Type conversion from java BigDecimal type to String type
It seems that java originally has a class called BigDecimal.
For the first time, declare a variable of type BigDecimal,
When I finally wanted to convert a BigDecimal type variable to a String type, I thought that I should use the valueOf() method, but BigDecimal seems to have a method for type conversion.
First of all, the BigDecimal type variable declaration & initialization is done at the top.
There are 3 variables (right, left, decimalValue) in all.
Next, store the calculation results of right and left in decimalValue with a switch statement.
And the type conversion, which is the point of interest,
String decimalValue1 = decimalValue.toString();
Is performing type conversion.
First, prepare decimalVlue1 to put the converted value
Next, I convert the decimalValue using the method that BigDecimal called toString() has.
