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.
