What is meaning of tilde symbol mean in the context of this PHP documentation page

0 votes

Please explain the significance of the tilde() symbol used in the following PHP manual sentence.

The size of a float is platform-dependent, although a maximum of ~1.8e308 with a precision of roughly 14 decimal digits is a common value (the 64 bit IEEE format).

Also,  Please let me know if, in other settings of the PHP language, such as in mathematics, the tilde () symbol has the meaning of negation or not (for example, A means "not A.").

Can PHP utilize the tilde () symbol in logical or mathematical expressions? If so, please give me a sample of a similar working code. If not, could you please explain the rationale?
