WebBasic Arithmetic Requirements. These requirements are common to all of the functions in this library. In the following table r is an object of type RealType, cr and cr2 are objects of type const RealType , and ca is an object of type const arithmetic-type (arithmetic types include all the built in integers and floating point types). Expression. WebSubtracting numbers of similar magnitudes; Multiplying and dividing; ... because our numbers are being converted from decimal into binary floating point. Many things that look fine in decimal, such as 0.1 or 0.4, are repeating decimals in binary. In binary, 0.5 has a lovely representation: 0.1. So when we convert 0.1 and 0.4 into binary, losing ...
