Converts the characters 0 through 9, plus, minus, e, E, and the decimal point (usually period) in a string to a floating-point number. This node can process strings that use fractional, exponential, or engineering notation.


use system decimal point?

A Boolean specifying whether to use the system decimal separator to designate a decimal point.

TRUE This node uses the localized decimal separator.
FALSE This node uses a period as the decimal separator.

Default: FALSE



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

If string contains the characters Inf or NaN, this node returns the LabVIEW values Inf and NaN, respectively.



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.

Default: 0



A numeric value whose representation determines the representation of number. The node ignores the actual value of this input.

Default: Extended-precision, floating point


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.



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 number, number is set to the maximum value for that representation.
