- Function Precision(x, y)¶
Precision¶
Precision(
x, ! (input) numerical expression
y ! (input) integer expression
)
Arguments¶
- x
A scalar numerical expression.
- y
An integer expression.
Return Value¶
The function
Precision
returns x rounded to y significant digits.
Note
The function
Precision
can be used in constraints of nonlinear mathematical programs. However, nonlinear solvers may experience convergence problems around the discontinuities of thePrecision
function.When the numerical expression contains a unit, the function
Precision
will first convert the expression to the corresponding base unit, before evaluating the function itself.
