Mathematical function for Decimal Digits

Question

Is there a way to get exact value for division operation like 1/24 to get exact value as

1/24 = 0.04166666666    

Answer 1

Just use a decimal. You can use the divide method if you want to specify a number of digits.

system.assertEquals(0, 1/24);
system.assertEquals(0.0416666666666666666666666666666667, 1.0/24);
system.assertEquals(0.04167, 1.0.divide(24, 5));
