round(number[, ndigits]) -floating point number
Round a number to a given precision in decimal digits (default 0 digits).
This always returns a floating point number. Precision may be negative.

Giving the Subject ("How to round a floating point to nearest 10?"),
there's a strong presumption that the OP would want the answer to be
180, not 200.

Which would be correct if your goal was to restrain to
1 significant digit.

Well, I can't read the OP's mind and the cases I HAVE encountered
are concerned about the number of significant digits. When
laboratories
report 3 digits, all my manipulations (ppm conversion, dividing
non-detect reporting limits by 2, comparison to TACO, etc. are
required to also have exactly 3 digits of significance).
>>print '%.2e' % 0.00000123456

>>print '%.2e' % 123456
1.23e+005
>>print '%.2e' % 0.123000456
1.23e-001
It all depends on what the OP actually wants. He's free to ignore
my example. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

I realize this probably a stupid question, but...is it safe to
round to the nearest integer by using int(round(val))?
I suspect it is fine, but wanted to be sure that weird floating point
representation on some platform might make it unsafe there (i.e. get the
wrong value due to the floating point value being an approximation) and
if so, is there a Better Way).

I need to implement a function to implement the rounding of floating point

type of the return value (integer or double).
// Integer calculation (fast)
int iround(const double x) {
return (x>=0 ? static_cast<int>(x + 0.5) : static_cast<int>(x + 0.5)

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
