The DECIMAL BRConfig.sys specification allows you to require the operator to type a decimal point when entering a numeric value that is formatted to include a fraction. This specification affects INPUT FIELDS/RINPUT FIELDS statements where the format of the numeric variable is X.X, as in the following example:
00010 INPUT FIELDS "10,10,N 7.2,R":NUMBER
The DECIMAL spec uses one of two parameters:
- ASSUMED (the start-up default), or
- REQUIRED. When DECIMAL REQUIRED is active, the operator needs to enter a decimal point for the above INPUT FIELDS value, only if a fractional part of a number is desired.
The following table compares the acceptable values for NUMBER when DECIMAL REQUIRED is active versus when DECIMAL ASSUMED is active.
| Value entered (using N 7.2) | DECIMAL REQUIRED | DECIMAL ASSUMED | |
| 1234.56 | 1234.56 | 1234.56 | |
| 1234 56 | err 0002 | 1234.56 | |
| 123456 | err 0002 | 1234.56 | |
| 1234 | 1234.00 | notice 12.34 | |
| 1234. | 1234.00 | 1234.00 |
The difference occurs when a decimal point is not entered. The DECIMAL spec may also be specified by the CONFIG command while Business Rules! is active.
