First, Q: please for i = = i + 1; provide a declaration to make the condition valid. Analysis: a number never equals 1 of its own, right? What if the number is infinitely large? Java enforces the use of IEEE binary floating-point arithmetic standard IEEE 754, which allows you to represent infinity with a double or float. Infinity plus 1 is infinitely large. If I is declared as

).　Boolean typeA Boolean type (BOOL) represents a condition that has two values: True and False. Where true indicates that the condition is set,Is true, and false indicates that the condition is not valid, which is false. A Boolean type is a subtype of an integer type. In fact, true is 1,False is 0. Thus, you can also use Boolean types to participate in mathematical operations, as are the results of using 1 and 0 to participate in the operation.　Floating-point typesA floating-point type (float)

expression: (long) Math.floor (A + 0.5d) The special case is as follows: If the argument is NaN, then the result is 0. If the result is a negative infinity or any value less than or equal to long.min_value, the result is equal to the Long.min_value value. If the argument is positive infinity or any value greater than or equal to long.max_value, the result is equal to the Long.max_value value. parameter:

. Of course, if it's 0.15+0.15 or 0.05+0.25, then it's fine. Therefore, do not test specific floating-point values.Range of values:Due to memory limitations, ECMAScript does not save all the values in the world, and the minimum value is generally preserved:number.min_value , the maximum value is saved in Number.MAX_VALUE . The out-of-range translates into a special Infinity value, or -infinity (negative

logically represents an empty object pointer, so typeof NULL returns "Object";② actually undefined values are derived from null values, so ECMA-262 specifies that the equality test for them returns true, that is, NULL = = undefined true;③ when a defined variable is used to hold an object in the future, it is better to initialize the variable to null.2.4 Boolean typeAny data type can call the Boolean () function, and in some flow control statements (such as the IF statement, the while statement,

Data typeEmphasis: in arithmetic expressions, byte,short,char all become int, and then all variables are converted to the highest-level type in their calculation.Basic data types and reference typesBasic data types: Byte 1, short 2, int 4, long 8, char 2 (equivalent to unsigned integer), float 4, double 8.

First, the type conversion method and should pay attention to the question: 1.Convert to Boolean:（1) with two-time non-operation(!):!! 5 ==> True（2) with a Boolean constructor:New Boolean (5) = = > TrueValue is converted to a Boolean type ofFalse：0，+0，-0，NaN，""(Empty string), Undefined,nullIn addition to the value of the above other values after the conversion forTrue, it is necessary to mention in particular:"0", New Object (), function () {}2.Convert to String type:（1) plus an empty string""：1

is the problem of rounding error. For example: 0.1 + 0.2 = 0.3 (15 0) 4 [4.3.3] The value range in js is Number. MIN_VALUE (5e-324) -- Number. MAX_VALUE (1.7976931348623157e + 308) [4.3.3.1] If a positive number range is exceeded, the output Infinity (positive Infinity) is exceeded, and the output Infinity (negative Infinity
