| 18 : | dpvc | 2731 | |
| 19 : | sh002i | 5553 | parserNumberWithUnits.pl - Implements a number with units. |
| 20 : | |||
| 21 : | gage | 4997 | =head1 DESCRIPTION |
| 22 : | |||
| 23 : | sh002i | 5553 | This is a Parser class that implements a number with units. |
| 24 : | It is a temporary version until the Parser can handle it | ||
| 25 : | directly. | ||
| 26 : | dpvc | 2731 | |
| 27 : | sh002i | 5553 | Use NumberWithUnits("num units") or NumberWithUnits(formula,"units") |
| 28 : | to generate a NumberWithUnits object, and then call its cmp method | ||
| 29 : | to get an answer checker for your number with units. | ||
| 30 : | gage | 4997 | |
| 31 : | sh002i | 5553 | Usage examples: |
| 32 : | |||
| 33 : | sh002i | 5555 | ANS(NumberWithUnits("3 ft")->cmp); |
| 34 : | ANS(NumberWithUnits("$a*$b ft")->cmp); | ||
| 35 : | ANS(NumberWithUnits($a*$b,"ft")->cmp); | ||
| 36 : | sh002i | 5553 | |
| 37 : | We now call on the Legacy version, which is used by | ||
| 38 : | num_cmp to handle numbers with units. | ||
