String To Number

StreamableKNIME Base Nodes version 3.7.1.v201901291053 by KNIME AG, Zurich, Switzerland

Converts strings in a column (or a set of columns) to numbers. If the node fails to parse a string, it will generate a missing cell and append a warning message to the KNIME Console with detailed information.


Choose the DataType that your string should be converted to.
Decimal Separator
Choose a decimal separator, which is used to mark the boundary between the integral and the fractional parts of the decimal string.
Thousands Separator
Choose a thousands separator used in the decimal string to group together three digits.
Accept type suffix, e.g. 'd', 'D', 'f', 'F'
When checked, the type suffix will be accepted, otherwise it fails to parse input like 1d. These suffixes are typically used in java-style programs to represent floating point numbers ('f' for float and 'd' for double). Default is not checked.
Column Selection
Move the columns of interest into the "Include" list

Input Ports

Arbitrary input data.
