The phrase "digit by" is grammatically correct and can be used in written English.
It is typically used to describe a mathematical operation, specifically division or multiplication. Example: "To find the answer, you must multiply the first digit by the second digit."
In all likelihood these two integers are equal, digit by digit if not exactly, then very nearly so.
And they have manually entered their findings, digit by digit, into one of the biggest spreadsheets you've ever seen.
(In "Manhattan by Numbers," an unemployed journalist works his way from Washington Heights to the East Village, descending digit by digit).
"Rather," they write in this week's Nature, "activating the concept of a digit by a mental calculation was sufficient to induce a colour experience".
In October the Central Committee met for the third time at the eighth plenum; top priority was assigned to reducing the rate of inflation to a single digit by 2010.
A range of compression types exist to cram more Y values onto each line that make use of substituting the first digit by a letter etc.
Moreover, in case the algorithm, which generates digit-by-digit the root of an integer N, did not stop with the digit for the units (N was not a perfect square), The Nine Chapters stated that another way of providing the result of the square root algorithm should be used: the root should be given in the form "side of N," which should be understood to mean "square root of N".
The algorithm uses a 32-bit floating-point arithmetic, and is based on a digit-by-digit iterative computation that does not require look-up tables, curve fitting, decimal-binary conversion, or division operations; the number of iterations depends on the precision defined by the user.
In Experiment 1, a simple digit-by-digit shifting process would allow a straightforward match with external representations.
This decrease of retrieval time was mainly due to the fact that the digits for each comparison in I-I could not be retrieved directly in a digit-by-digit shifting manner.
In Experiment 1, participants could use a digit-by-digit shifting process to retrieve the digit in working memory for each comparison because the response order was consistent with the encoding order, both from the top to the bottom.
