C++ Syntax

bool

MKI_ConvertStringDouble(

double& f_rValue,

const LPCWSTR f_pszText,

HWND f_hParentWindow );

Converts a string's content into a double value, with terms like (0.5+2.0)/3 being evaluated.

Parameters

Value

[double&] Address of variable to receive the evaluated double value.

Text

[const LPCWSTR] Text containing the double value to be converted. This text may either include a single numeric value or a complete term like (0.5+2.0)/3. For a description of the term syntax see Mathematical Terms.

ParentWindow

[HWND] If this handle is not nullptr, the corresponding window will be used as parent window of any error message occuring during term evaluation. If ParentWindow is nullptr, no error message is displayed.

Return Value

Returns true if successful, false if not.

Comment

This procedure will allow the full possible double value range. The assumed default units are [mm] for lengths and [deg] for angles.

The term evaluation is limited to 100 bracket levels and 1000 elements per bracket level.
