<strong>Number fields</strong>: When you add a number field you can choose from three types: <em>decimal</em>, <em>float</em>, and <em>integer</em>. The <em>decimal</em> number field type allows users to enter exact decimal values, with fixed numbers of decimal places. The <em>float</em> number field type allows users to enter approximate decimal values. The <em>integer</em> number field type allows users to enter whole numbers, such as years (for example, 2012) or values (for example, 1, 2, 5, 305). It does not allow decimals.
