Fract/Exp String To Number

Interprets the characters 0 through 9, plus, minus, e, E, and the decimal point (usually period) in string starting at offset as a floating-point number in engineering notation, exponential, or fractional format and returns it in number. The connector pane displays the default data types for this polymorphic function.

use system decimal point defines the decimal separator. If TRUE (default), the decimal separator uses the localized decimal separator. If FALSE, the decimal separator is a period.
string can be a string, a cluster of strings, an array of strings, or an array of clusters of strings. If the data type of string is a number, the function interprets it as ASCII codes for characters. If string contains the characters Inf or NaN, this function returns the LabVIEW values Inf and NaN, respectively.
offset is the starting position and must be numeric. The offset of the first character in the string is 0. If unwired or if less than 0, the default is 0.
default is any object of numeric representation and specifies the numeric representation for number. The default is an extended-precision, floating-point value of 0.
offset past number is the index in string of the first character following the number. offset past number reflects the value from the last string if you input an array of strings.
number can be a number, a cluster, an array of numbers, or an array of clusters, depending on the structure of string. The following table shows how the values of string, offset, and default affect number.
