This article mainly introduces how to convert a numeric string into a corresponding value in vb. It is very detailed and has a certain reference value. Interested friends must read it!

In vb, to convert a numeric string into a corresponding numerical value, the function should be "Val ()"; the grammatical format of this function is "Val (SForce VMagneCode)", meaning: convert the string S to the corresponding numeric type and assign a value to V, if there are non-numeric characters in the string, then "Code 0", Code can return the position of non-numeric characters.

To convert a numeric string to a corresponding numeric value in vb, the function you should use is "Val ()".

The Val function can convert character data composed of numeric symbols (including positive and negative signs and decimal points) into corresponding numeric data.

Use format usage:

Val (Smage VMagneCode)

Converts the string S to the same numeric type as V and assigns it to V, and if there is a non-numeric character in the string, the V Code is used to return the position of the non-numeric character.

Description:

If a non-numeric character appears in the string, only the part preceding the non-numeric character is converted; if the first character of the string is not a numeric symbol, a numeric zero is returned, but leading spaces are ignored.

Example:

Text1.text = "10"

Text2.text = "11"

Text3.text = text1.text+text2.text

You should get 10: 11 (the result is 21), but return 1011, which is because it is a character operation.

Text1.text = "10"

Text2.text = "11"

Text3.text = val (text1.text) + val (text2.text)

The return is 21.
