Re: How to create a function to evaluate numeric expression

[Fabien COULLOMB]

Thanks for you answer.

In fact I need this function, to take in consideration packaging and units of products in my application.

I have in entering parameters some brut quantity, and i need to convert this quantity in net quantity. For example, in brut I have 8.23 and in net I need 12. In fact (for this example that's mean I want a multiple of 6). But according the product corresponding the packaging could be different, and I have a lot of products, the packaging formula is like !((ZQTE/6)+.49)/100;.2!*600 ( the !! delimit the expression, the right part after the ; is the ruond to apply, and this formula is directly made by an application user when a product is created.And the formula could be very different.

I have began to try to create a function by parsing my string, but currently It's running only with '*' and '+', and not yet with the accolades. That's will be very hard, exactly like you say (as teaching a dog...)
