The scaling factor specifies the number of digits to the right of the decimal point+ADs- it ranges from 0 through 28. With a scale of 0 (no decimal places), the largest possible value is 79,228,162,514,264,337,593,543,950,335. With 28 decimal places, the largest value is 7.9228162514264337593543950335, and the smallest nonzero value is 0.0000000000000000000000000001 (1E-28).+ADw-/P+AD4- +ADw-P+AD4-Appending the literal type character +ADw-B+AD4-D+ADw-/B+AD4- to a literal forces it to the +ADw-B+AD4-Decimal+ADw-/B+AD4- data type. Appending the identifier type character +ADw-B+AD4AQAA8-/B+AD4- to any identifier forces it to +ADw-B+AD4-Decimal+ADw-/B+AD4-. You might need to use the +ADw-B+AD4-D+ADw-/B+AD4- type character to assign a large value to a +ADw-B+AD4-Decimal+ADw-/B+AD4- variable or constant, as the following example shows:+ADw-/P+AD4- +ADw-PRE class+AD0AIg-code+ACIAPg-Dim BigDec1 As Decimal +AD0- 9223372036854775807 ' No overflow.
