TheString.valueOf()function in Java returns a string representation of any class. Syntax: String.valueOf(AnyObject) Input parameter: Any object in class, like BigDecimal Returns: string version of a provided object, in this case, BigDecimal Object Example: MathContextmc=newMathContext(3);BigDeci...
It is used when the integers involved are larger than the limit of thelongtype.For example, the factorial of 50 is30414093201713378043612608166064768844377641568960512000000000000.This value is too big for anint or longdata type to handle. It can only be stored in aBigIntegervariable. It is widely ...
Furthermore,we useBigDecimalfor high-precision arithmetic, calculations requiring control over the scale, and rounding off behavior. One such example is calculations involving financial transactions. We can convert aStringintoBigDecimalin Java using one of the below methods: BigDecimal(String)constructor B...

A decimal number could, for example, encode a mantissa of 23456 and an exponent of -2, and this would expand to 234.56. Decimals, because the arithmetic isn't hard-wired into the CPU, are slower than floats, but they are ideal for anything that involves decimal numbers and needs those ...

In the case of divide, the exact quotient could have an infinitely long decimal expansion; for example, 1 divided by 3. If the quotient has a nonterminating decimal expansion and the operation is specified to return an exact result, an ArithmeticException is thrown. Otherwise, the exact ...
