Limitation of function EXP()

[RhoSigma]

Once again updated/clarified the EXP wiki page. Got a bit confused by the C++ function names respectively passed parameter types.

In fact @Jack was right, EXP is not really supporting _FLOAT precision, although you may pass such a value, it's still limited to 709.something, as DOUBLE runs through the same C++ function and so the limit of the smaller type must be taken.
