Decimal String to Number (G Dataflow)

Last Modified: August 31, 2018

Converts the numeric characters in a string to a decimal integer.



The string that you want to convert. This input can also be any data type that contains only strings, such as an array or cluster of strings.



The number of characters into the input string at which this node begins its operation.

The offset of the first character in the input string is 0. If offset is beyond the end of the input string, this node returns an empty string.


A character refers to a code point, a numeric unit between 0 and 10FFFF16, defined by the Unicode standard for encoding. For more information about code points, research Unicode.

Default: 0



A numeric value whose representation determines the representation of number.

Default: 32-bit signed integer


offset past number

The index in string of the first character following the number.

If string is an array of strings, offset past number reflects the offset within the last string.


A character refers to a code point, a numeric unit between 0 and 10FFFF16 that is subscribed meaning by the Unicode standard for encoding. You can research Unicode for more information about code points and other units of meaning for encoding.



The result of converting string into a number. The structure of number matches the structure of string. For example, if string is an array of strings, number is an array of numbers.

If the input string represents a number outside the range of the representation of this output, this output returns the maximum or minimum value for the representation. For example, if the input string is 300, and the representation of this output is an 8-bit signed integer, this output returns 127.

The following table shows how the values of string, offset, and default affect number.
string offset default offset past number number Comments
13ax 0 0 2 13
–4.8bcde conversion 0 0 2 –4 Because an integer is being converted, conversion stops at the decimal point.
a49b 0 –9 0 –9 default is used since no digits were read.

Where This Node Can Run:

Desktop OS: Windows

FPGA: All devices (only within an optimized FPGA VI)

Web Server: Supported in VIs that run in a web application
