float() converts a value to a float type.

Function type signature

(v: A) => float

Parameters

(Required) Value to convert.

Examples

• Convert a string to a float
• Convert a scientific notation string to a float
• Convert an integer to a float
• Convert all values in a column to floats

Convert a string to a float

float(v: "3.14")// Returns 3.14

Convert a scientific notation string to a float

float(v: "1.23e+20")// Returns 1.23e+20 (float)

Convert an integer to a float

float(v: "10")// Returns 10.0

If converting the _value column to float types, use toFloat(). If converting columns other than _value, use map() to iterate over each row and float() to convert a column value to a float type.
