Talk:Truncation

From Wikipedia, the free encyclopedia

This needs a link to floor function. Is it the same for negative numbers?

[edit] Quality Of English

"like when someone uses only the first few terms of an infinite series, or when one calculates an integral by approximating the area by finite trapezoids, or when the derivative of a function is found by using a finite deltax"

I dislike the use of "like", as well as this drawn on sentence. Could someone with more insight into the expected standards for English on Wikipedia please correct this? Thanks. —Preceding unsigned comment added by 64.230.94.119 (talk) 05:08, 5 January 2008 (UTC)

[edit] TeX

Hi, i just added the TeX and Rounding/floor function info. I made it easy myself by only allowing to use positive real numbers to be truncated. If you are shure it can be done for any real number, go ahead. --Abdull 16:57, 8 March 2006 (UTC)

I think truncation is referred to as truncating a mathematical procedure, like using a finite number of terms in an infinite series, or approximating an integral as a trapezoid, etc. What is referred as truncation in wikepedia is called chopping. Truncation and round off and chopping are used interchangeably so much that it can be confusing to the reader.

[edit] More general

In mathematics, truncation is the term used for reducing the number of digits right of the decimal point [...]

Generally speaking, you can also truncate a value before the decimal point. Truncating 817.23 two digits before the decimal point will make 800. --Abdull 17:06, 8 March 2006 (UTC)
