In numerical algorithms, machine epsilon measures the degree to which this operation affects the outcome of floating-point operations, and the degree to which the resulting errors are amplified is described by the condition number. For a variable x, x minus this function of x yields a sawtooth wave. To express an arbitrary-precision number using a given number of significant digits, one must perform this operation. One form of it is written using square brackets with the bottom part removed and is called "ceiling". For 10 points, name this oper

One form of it is written using square brackets with the bottom part removed and is called "ceiling". For 10 points, name this operation, contrasted with truncation, in which a number is approximated by a less-precise number, and which might convert 3.7 to 4.
