Summary

Function: integer llCeil( float val );
0.0 Forced Delay
10.0 Energy

Returns an integer that is the integer value of val rounded towards positive infinity (return >= val).

• float val Any valid float value

Caveats

The returned value is -2147483648 (0x80000000) if the arithmetic result is outside of the range of valid integers (-2147483648 to 2147483647)

Examples

<lsl> default {

  state_entry()
  {
      llSay(PUBLIC_CHANNEL, "The ceil value of -4.5 is: " + (string)llCeil(-4.5));

// "The ceil value of -4.5 is: -4"

      llSay(PUBLIC_CHANNEL, "The ceil value of -4.9 is: " + (string)llCeil(-4.9));

// "The ceil value of -4.9 is: -4"

      llSay(PUBLIC_CHANNEL, "The ceil value of -4.1 is: " + (string)llCeil(-4.1));

// "The ceil value of -4.1 is: -4"

      llSay(PUBLIC_CHANNEL, "The ceil value of 4.5 is: " + (string)llCeil(4.5));

// "The ceil value of 4.5 is: 5"

      llSay(PUBLIC_CHANNEL, "The ceil value of 4.9 is: " + (string)llCeil(4.9));

// "The ceil value of 4.9 is: 5"

      llSay(PUBLIC_CHANNEL, "The ceil value of 4.1 is: " + (string)llCeil(4.1));

// "The ceil value of 4.1 is: 5"

   }
