Question

How can we round off a number to the nearest 10 in php   Say I have 23  what code would I use to round it off to 30

User · Answer

We can  cheat  via round with   rounded   round  roundee   10    10    We can also avoid going through floating point division with  function roundToTen  roundee       r    roundee   10    return   r  lt   5     roundee -  r    roundee    10 -  r       Edit  I didn t know  and it s not well documented on the site  that round now supports  negative  precision  so you can more easily use   round   round  roundee  -1     Edit again  If you always want to round up  you can try  function roundUpToTen  roundee       r    roundee   10    if   r    0      return  roundee    return  roundee   10 -  r

I wanted to round up to the next number in the largest digits place  is there a name for that    so I made the following function  in php      Get the max value to use in a graph scale axis     given the max value in the graph function getMaxScale  maxVal         maxInt   ceil  maxVal        numDigits   strlen  string  maxInt -1    this makes 2150- gt 3000 instead of 10000      dividend   pow 10  numDigits        maxScale  ceil  maxInt   dividend     dividend      return  maxScale

floor   will go down     ceil   will go up    round   will go to nearest by default   Divide by 10  do the ceil  then multiply by 10 to reduce the significant digits    number   ceil  input   10    10    Edit   I ve been doing it this way for so long   but TallGreenTree s answer is cleaner

There are many anwers in this question  probably all will give you the answer you are looking for  But as  TallGreenTree mentions  there is a function for this   But the problem of the answer of  TallGreenTree is that it doesn t round up  it rounds to the nearest 10  To solve this  add  5 to your number in order to round up  If you want to round down  do -5   So in code   round  num   5  -1     You can t use the round mode for rounding up  because that only rounds up fractions and not whole numbers   If you want to round up to the nearest 100  you shoud use  50

This can be easily accomplished using PHP  fmod  function  The code below is specific to 10 but you can change it to any number     num 97   r fmod  num 10    r 10- r   r  num  r  return  r    OUTPUT  100

My first impulse was to google for  php math  and I discovered that there s a core math library function called  round    that likely is what you want

I was actually searching for a function that could round to the nearest variable  and this page kept coming up in my searches  So when I finally ended up writing the function myself  I thought I would post it here for others to find   The function will round to the nearest variable   function roundToTheNearestAnything  value   roundTo         mod    value  roundTo      return  value   mod lt   roundTo 2  - mod  roundTo- mod       This code   echo roundToTheNearestAnything 1234  10    lt br gt    echo roundToTheNearestAnything 1234  5    lt br gt    echo roundToTheNearestAnything 1234  15    lt br gt    echo roundToTheNearestAnything 1234  167    lt br gt      Will output   1230 1235 1230 1169
