ILOG OPL Development Studio Language Reference Manual

Integer and float expressionsInteger expressionsInteger expressions are constructed from integer constants, integer data, integer decisionvariables, and the traditional integer operators such as +, -, *, div, mod (or%). The operatordiv represents the integer division (for example, 8 div 3 == 2) and the operator modor % represents the integer remainder. OPL also supports the function abs, which returns theabsolute value of its argument, and the built-in constant maxint, which represents the largestinteger representable in OPL. Note that expressions involving large integers may produceoverflow.Example for intNote the result:int a=maxint+2;float b=infinity+2;execute{writeln(a);writeln(b);}gives-2147483647InfinityMost of these expressions (such as % or div) are not available for constraints defined inCPLEX models but are available for CP models. See also Constraints available in constraintprogramming.Float expressionsFloat expressions are constructed from floats, float data and variables, as well as operatorssuch as +, -, /, *. In addition, OPL contains a float constant infinity to represent [replacewith sign “infinity”] and a variety of float functions, depicted in OPL functions in the LanguageQuick Reference.Conditional expressionsConditional expressions are expressed like this:92I L O G O P L D E V E L O P M E N T S T U D I O L A N G U A G ER E F E R E N C E M A N U A L
