Are there any best practices for converting variables to decimal numbers in PHP?

When converting variables to decimal numbers in PHP, it is important to ensure that the variable is of the correct type and format before performing the conversion. One common method is to use the `floatval()` function to convert a variable to a decimal number. This function will convert a variable to a floating-point number, which is suitable for decimal calculations in PHP. 

// Example variable to convert to decimal number
$number = "123.45";

// Convert the variable to a decimal number using floatval()
$decimalNumber = floatval($number);

// Output the decimal number
echo $decimalNumber;
