# Arithmetic built-in functions

The following table describes some of the useful built-in functions that extend the basic set of numeric operands.
 Function Arguments Returned value ABSOLUTE value AS INTEGER or DECIMAL INTEGER or DECIMAL — The absolute value of the numeric value. EXP base AS INTEGER or DECIMAL, exponent AS INTEGER or DECIMAL INTEGER or DECIMAL — The result of raising the base number to the exponent power. LOG expression AS DECIMAL, base AS INTEGER or DECIMAL DECIMAL — The logarithm of the expression using the specified base. The base is optional; the natural logarithm, base (e), is returned by default. MAXIMUM Two or more expressions AS INTEGER or DECIMAL INTEGER or DECIMAL — The largest value of the expressions. MINIMUM Two or more expressions AS INTEGER or DECIMAL INTEGER or DECIMAL — The smallest value of the expressions. MODULO Special syntax: expression MODULO base INTEGER — The remainder after division. The expression and base must be INTEGER values. RANDOM low-value AS INTEGER, high-value AS INTEGER INTEGER — A random INTEGER value between the low-value and the high-value (inclusive). There is a Random (–rand) ABL startup option that determines whether a different set of values is returned for each OpenEdge session. ROUND expression AS DECIMAL, precision AS (positive) INTEGER DECIMAL — The DECIMAL expression rounded to the number of decimal places specified by the precision. The rounding is down for all values beyond the precision that are less than .5, and up for all higher values. SQRT expression AS INTEGER or DECIMAL DECIMAL — The square root of the expression. TRUNCATE expression AS DECIMAL, precision AS (non-negative) INTEGER DECIMAL — The expression truncated to the specified precision.
