| suppose i use variables a and b which are defined as decimals and gets

If you define the variable as Decimal, the variable will hold a Decimal.
| c=a-b D
a is a variable of type Decimal, it will return a Decimal value,
literals are not involved here, so you don't need the "literal type
character D".
The D is part of a Literal (constant if you will) value.
2.2 is a literal
a is a variable
b is a variable
c is a variable
2.2 is a Double literal
2.2D is a Decimal literal
2.2F is a Single literal (the F stands for Float).

| Dave,
| Try:
| >
| | Dim a, b As Decimal
| | a = 2.2D
| | b = 0.4D
| | Response.Write(a - b)
| >
| | But this gives: 0,8000001 (rendered according my regional settings):
| Is given as that is the approximate value that a Single can hold. A
Single
| holds base 2 floating point numbers, some (most) base 10 floating point
| numbers cannot be exactly represented

| NOTE: The D in 2.2D indicates it is a Decimal literal as opposed to 2.2
| which is a Double literal, as opposed to 2.2F which is a Single literal.

| | Hi,
| |
| | Dim a, b As Single
| | a = 2.2
| | b = 0.4
| | Response.Write(a - b)
| |
| | This gives: 1,8 (rendered according my regional settings)
| |
| |
| | But this gives: 0,8000001 (rendered according my regional settings):
| | Dim a, b As Single
| | a = 1.2
| | b = 0.4
| | Response.Write(a - b)
| |
| |
| | Any explantion for this, and how to solve this?? ( i rounded on two
| digits)
| | Thanks
| | Dave
