VB stores symbolic and literal constants internally using the simplest data type possible; this means that most common numeric constants-such as zero or one-are stored as Integers. If you use these constants in floating point expressions you can speed up your code using a constant of appropriate type, as in: Click here to copy the following block value# = value# + 1#. This forces the compiler to store the constant in Double format, thus saving one implicit conversion at runtime. Alternatively, you can declare and use a symbolic constant of a well defined type, as in: Click here to copy the following block Const ONE As Double = 1
