regular expression or format into string (nevermind)

[ThijsBoeree]

Solved it,

I can use string to fractional number!

Hi,

I have a 2D string array from a multicolumn list box, and i want to check if every value is valid number, the numbers can be a single and can have negative values. Does anyone knows which regular expression i need to check this, or is there an ever better way doing it?

Best regards,

Thijs

Hi

I know, but this was to simple, i wanteded a zero if a character was filled in the multicolumn listbox, and when using string to fractional number it does!
