public static bool Evaluate(string expression,
out T value);
### Parameters

### Returns

**bool**
Indicates whether expression could be evauated successfully.

### Description

Evaluates a math expression and returns the result.

The expressions that can be evaluated support:

- arithmetic operators
`a+b`

, `a-b`

, `a*b`

, `a/b`

,
- power (
`a^b`

) and modulo (`a%b`

) operators,
- parentheses,
- math functions
`sqrt(a)`

, `floor(a)`

, `ceil(a)`

, `round(a)`

,
- trigonometic functions
`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.
