integer llRound(float fval)

Round a float to the nearest integer.

The float value to be rounded.

Returns the integer value that is the nearest to fval. If the decimal part is exactly .5, it will be rounded up (towards positive infinity).

• The function returns -2147483648 (Hex. 80000000) for float values of 2147483648.0 or bigger, or less than -2147483648.0.

integer i;
// Any float between 2.5 and approx. 3.4999998 will cause the function to return 3
// (3.4999998 is the biggest possible float less than 3.5, due to float limitations)
i = llRound(2.6);    // i will become 3
i = llRound(3.3);    // i will become 3
i = llRound(3.499);  // i will become 3
i = llRound(3.5);    // i will become 4
i = llRound(3.501);  // i will become 4
// Any float between -3.5 and approx. -2.5000002 will cause the function to return -3
// (-2.5000002 is the smallest possible float greater than -2.5, due to float limitations)
i = llRound(-3.3);   // i will become -3
i = llRound(-3.499); // i will become -3
i = llRound(-3.5);   // i will become -3
i = llRound(-3.501); // i will become -4

• llCeil rounds always towards positive infinity (e.g. 1.1 is rounded up to 2.0, and -1.1 is rounded up to -1.0).
• llFloor rounds always towards negative infinity (e.g. 1.1 is rounded down to 1.0 and -1.1 is rounded down to -2.0).
