This is because javascript uses floating point numbers to represent all numbers, see w3schools. Floating point numbers cannot represent all numbers, because they only have a certain amount of accuracy. 16.56 is one of the (many) numbers that cannot be represented fully. This is similar to the way that we can't represent 1/3 accurately in decimal, because it needs a recurring decimal. See this discussion for more detail.

Two options to get round this are round to two decimal places or possibly do all operations multiplied by 100 then divide by 100 when you display the result.
