Convert exponential number to decimal in php
Is there a way to convert an exponential number to a whole number in PHP using built in functions? A format function?
1.2378147769392E+14 to 123781477693917
回答1:
number_format(1.2378147769392E+14,0,'','')
However, for working with large numbers, if you want to keep precision, you should look into BCMath extension
