The **`parseFloat()` function** takes a string as input, converts it to float, and returns the result. 





# 
## Syntax


## Parameter 
The only parameter for this function is a `string`.

## Return value 

The function returns a floating-point number that is parsed from the `string`.
 - Only the first number is converted to float and returned if the string has more than one number separated by a space. 
 - Extra spaces at the beginning and the end are ignored. 
 - Any alphabets are ignored if they are at the end.
 - `NaN` is returned if the first non-whitespace character cannot be turned to float. 

## Code


console.log( parseFloat("56.019") )
console.log( parseFloat("    56.019   abc") )
console.log( parseFloat("57") )
console.log( parseFloat("68.9 55") )
console.log( parseFloat("abc 56.019") )
