Closeexpression | A string containing a mathematical expression (e.g. "4+3"). |
value | The result of the expression evaluation. Supported types are: int , float , long , double . |
bool Indicates whether expression could be evauated successfully.
Evaluates a math expression and returns the result.
The expressions that can be evaluated support:
a+b
, a-b
, a*b
, a/b
,a^b
) and modulo (a%b
) operators,sqrt(a)
, floor(a)
, ceil(a)
, round(a)
,cos(a)
, sin(a)
, tan(a)
(argument expressed in radians), and a constant pi
.If the expression can not be evaluated, the function returns false
and the result value is set to zero.
