Solve equation numerical

Hi,

is there a in built function in Igor to solve an equation numerical?
Something like:
Variable d = solve(x, 0=x-exp(x))

and then d is the numer, which solves the equation.

Couldnt find anything...
Thank you for you help!

The contributed code snippets contain no detailed help functions, but many applied math texts discuss Muller's method.
