Js--codewars--human readable Time-math object, parseint ()

Problem Description:

Write a function, which takes a non-negative integer (seconds) as input and returns the time in a human-readable format ( c0/>)

• HH= hours, padded to 2 digits, range:00-99
• MM= minutes, padded to 2 digits, range:00-59
• SS= seconds, padded to 2 digits, range:00-59

The maximum time never exceeds 359999 ( 99:59:59 )

You can find some examples in the test fixtures.

My answer:

1 functionhumanreadable (seconds) {2   //TODO3   varhh=0; mm=0; Ss=0;4   if(seconds>359999) {return false;}5Hh=parseint (seconds/3600);6Mm=parseint ((seconds-hh*3600)/60);7Ss=parseint ((seconds-hh*3600)%60);8Hh= (hh<10)? " 0 "+hh:hh;9Mm= (mm<10)? " 0 "+mm:mm;TenSs= (ss<10)? " 0 "+Ss:ss; One     return(hh+ ":" +mm+ ":" +SS). toString ();  A}

Excellent answer:

1 function humanreadable (seconds) {2   var function return (x < 10)? "0" +x:x;} 3   return pad (parseint (seconds/(60*60)) + ":" +4          pad (parseint (SECONDS/60)) + ":" +5           pad (seconds%)6 }

JS take the whole to take the remainder

Method	Meaning	Results
parseint (5/2);	Discard the fractional part, preserving the whole number of parts	2
Math.ceil (5/2);	Rounding up, with decimals on the entire number of parts +1	3
Math.Round (5/2);	Rounded	3
Math.floor (5/2);	Rounding down	2

1, conversion function (valid for string type, otherwise non)

parseint ()//Convert a string to an integer

parseint ("123blue"); Return 123

parseint ("22.5"); return 22

Parsefloat ()//Convert a string to a floating-point number

Parsefloat ("1234blue"); Return 1234.0

Parsefloat ("22.5"); return 22.5

2, forcing type conversions

Boolean (value)----Converts the given value to a Boolean type

The Boolean () function returns True when the value to be converted is a string of at least one character, a non-0 number, or an object (this is discussed in the next section). If the value is an empty string, the number 0, undefined, or null, it returns FALSE.

Number (value)----Converts the given value to a digit (which can be an integer or a floating point)

string (value) ----to convert the given value to a string

Weak-type conversion of 3,JS (arithmetic operations only, string-to-number conversion is implemented)

var str= "012.345";

x=x*1; Return number 12.345

4. Methods for other commonly used math objects

Math.Abs (-1); 1

Math.log (1); Logarithm of base E, 0

Math.max (a); 3

Math.min (1,23); 1

Math.random (); Returns the number of random numbers between 0~1

Math.pow (2,3); 2 of the 3-time Square is 8.

MATH.SQRT (9,3); The square root of 8 is 2
