Use double instead of float

double d = 40959999/100.00f;

Double and Float have inherent imprecision that is impossible to avoid (more info on the why here). Using a double you may not have your number rounded in this scenario but not in all. If you work with something that should never be rounded (like prices), you should be using BigDecimal instead.

Implement your int value like shown. Rather than using float use BigDecimal instead.

BigInteger b1 = BigInteger.valueOf(40959999); 
int scale = 2;
BigDecimal d1 = new BigDecimal(b1, scale); 
System.out.println(d1);

run:
409599.99
