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!!
