Andromeda allows you to specify a minimum and maximum value for a column. These can be defined when the column is defined (outside of a table), or they can be defined when the column is placed into a table. Use the properties "valuemin" and "valuemax" to establish this constraint.
# Define a percent as a numeric from
# 1 to 100
column percent:
type_id: numb
colprec: 3
colscale: 0
valuemin: 0
valuemax: 100
# Define another percent as a decimal
# from zero to .999
column decimalpercent:
type_id: numb
colprec: 3
colscale: 3
valuemin: 0
valuemax: .999
# Put a column into a table
table example:
column percent_sportseffort:
description: Sports figures often give 110%
suffix: _sportseffort
valuemax: 110
