RE: How to round a floating point to nearest 10?

P: n/a
>>round(76.1, -2)
100.0
>>round(76.1, -1)
80.0
>>round(76.1)
76.0

builtin function round, will work for you......
Help on built-in function round in module __builtin__:
round(...)
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.

good luck..

I want my 76.1 to be rounded to decimal 80 and 74.9 to decimal 70.
How can I achieve that?

7e+01

8e+01
But:
>>print '%.0e' % 176.1
2e+002

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.
