Let’s suppose I have a string that contains “7.2769482308e+01” (this number came from 3rd party software, I cannot control the format).
What is the cheapest way to convert it into decimal
The only solution I can think of is to split decimal + exponential part and use multiplication. But may be there some built it function to do the same?
NOTE: Guys, yes, I’ve read Convert exponential to a whole number in PHP and Convert exponential number to decimal in php. And that questions are irrelevant, since they already have a number, but I have a string.
What about a simple cast to a float value ?
$string = "7.2769482308e+01"; $float = (float) $string;
I had success using
number_format(1.2378147769392E+14, 0, '', '') which was originally provided by this question.
This also works when the value is a string, like so:
number_format("1.2378147769392E+14", 0, '', ''). Go ahead, give it a try.
Here is a very cheap one:
$float = "7.2769482308e+01" + 0;
