Introduction

In this blog post we will discuss about the toFloat() function. This function allows developers to convert various data types to floating-point numbers, enabling them to perform arithmetic operations, comparisons, and other calculations.

toFloat() function

This function converts a value and returns the value of floating point value. If any value are not convertible to floating point they will be null.

Example:

-- toFloat()
SELECT * FROM cypher('expr', $$
    RETURN toFloat(1.3)
$$) AS (toFloatList agtype);
 tofloatlist 
-------------
 1.3
(1 row)

This function is in Apache AGE, and it helps the data manipulation of a database. Suppose you have a database table with a column that stores numeric values as strings, and you want to perform calculations or analysis on those values as floating-point numbers. However, some of the values may not be directly convertible to floats, this function can help you with it!!
