struct nlohmann::basic_json< ObjectType, ArrayType, StringType, BooleanType, NumberIntegerType, NumberUnsignedType, NumberFloatType, AllocatorType, JSONSerializer >::lexer::strtonum

parse string into a built-in arithmetic type as if the current locale is POSIX.

Note

in floating-point case strtod may parse past the token's end - this is not an error

any leading blanks are not handled
