In Access 2007 CSV Export: Disable Scientific Notation.
When exporting a CSV from Access 2007, it automatically converts decimals into scientific notation. Unfortunately the tool that receives them treats these fields as text, and displays them as is. The values being exported are from a query being run against some Excel linked tables, and they appear perfectly in the query view. Is there...
Parsing scientific notation sensibly?
I want to be able to write a function which receives a number in scientific notation as a string and splits out of it the coefficient and the exponent as separate items. I could just use a regular expression, but the incoming number may not be normalised and I'd prefer to be able to normalise and then break the parts out. A colleague ha...
Why use 'e0' at the end of a defined constant in c?
Hi Everyone, I'm trying to debug a problem with a perl application that calls some c programs to do text editing. BATCH_JV_CSH_MAX is used to test the maximum value of an amount field.

Why in SAS does a numeric literal in scientific notation give a different number to the number written out explicitly?
The following SAS code: data _null_; format t u best32.; t = 10000000000000000000000000; u = 1e25; put t u; if t ne u then put 'diff'; run; on my Windows machine prints out: 10000000000000000905969664 9999999999999998758486016 diff While I understand that only the first 15-16 digits are to be trusted, why do they give dif...
How can I print a huge number in Lua without using scientific notation?
I'm dealing with timestamps in Lua showing the number of microseconds since the Epoch (e.g. "1247687475123456"). I would really like to be able to print that number in all its terrible glory, but Lua insists on printing it in scientific notation. I've scoured the available documentation about printing a formatted string, but the only av...
Java DecimalFormat Scientific Notation Question
Hello. I'm using Java's DecimalFormat class to print out numbers in Scientific Notation. However, there is one problem that I have.

Reading ASCII numbers using "D" instead of "E" for scientific notation using C
Hello, I have a list of numbers which looks like this: 1.234D+1 or 1.234D-02. I want to read the file using C. The function atof will merely ignore the D and translate only the mantissa. The function fscanf will not accept the format '%10.6e' because it expects an E instead of a D in the exponent. When I ran into this problem in Pytho...
