Talk:Truncation

From Wikipedia, the free encyclopedia

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

[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)
