log
Returns the logarithm of the input.
Syntax
floatExpr log(floatExpr x)
Parameters
-
x: a floating-point expression.
Description
The function log computes the logarithm of x.
The argument x is automatically constrained to be positive. Therefore if x cannot be positive then the model becomes infeasible.
Example
a = intVar(1..8);
b = intVar(1..8);
log(a) >= 2+log(b);
