  • LaTeX Double Spacing

    - by aaa
    hello. What is the actual precision of long double on Intel 64-bit platforms? is it 80 bits padded to 128 or actual 128 bit? if former, besides going gmp, is there another option to achieve true 128 precision?

  • Escape apostrophes inside double quoted strings (Javascript)

    - by George Sheppard
    Say i have a string that i need to evaluate in javascript such as : window.some_class.update( 'Runner', 'update_runner', '{"runner":{"id":"1","name":"Nin's Lad" } }'); In order for eval() to evaluate it, i need to escape the apostrophe in runner_name (Nin's Lad). Is this possable with regex? I dont want to escape the single quotes around Runner and update_runner. I'd just like to escape any single quotes inside double quotes. Thanks,

  • Exact textual representation of an IEEE "double"

    - by CyberShadow
    I need to represent an IEEE 754-1985 double (64-bit) floating point number in a human-readable textual form, with the condition that the textual form can be parsed back into exactly the same (bit-wise) number. Is this possible/practical to do without just printing the raw bytes? If yes, code to do this would be much appreciated.

  • Regular expression for pipe delimited and double quoted string

    - by Hiren Amin
    I have a string something like this: "2014-01-23 09:13:45|\"10002112|TR0859657|25-DEC-2013>0000000000000001\"|10002112" I would like to split by pipe apart from anything wrapped in double quotes so I have something like (similar to how csv is done): [0] => 2014-01-23 09:13:45 [1] => 10002112|TR0859657|25-DEC-2013>0000000000000001 [2] => 10002112 I would like to know if there is a regular expression that can do this?

  • Can someone explain this 'double negative' trick?

    - by ProfessionalAmateur
    Hello, I am by no means an expert at javascript, but I have been reading Dave Pilgrim's "Dive into HTML5" webpage and he mentioned something that I would like a better understanding of. He states: "Finally, you use the double-negative trick to force the result to a Boolean value (true or false)." function supports_canvas() { return !!document.createElement('canvas').getContext; } If anyone can explain this a little better I would appreciate it!

  • How to bind a double precision using psycopg2

    - by user337636
    I'm trying to bind a float to a postgresql double precision using psycopg2. ele = 1.0/3.0 dic = {'name': 'test', 'ele': ele} sql = '''insert into waypoints (name, elevation) values (%(name)s, %(ele)s)''' cur = db.cursor() cur.execute(sql, dic) db.commit() sql = """select elevation from waypoints where name = 'test'""" cur.execute(sql_out) ele_out = cur.fetchone()[0] ele_out 0.33333333333300003 ele 0.33333333333333331 Obviously I don't need the precision, but I would like to be able to simply compare the values. I could use the struct module and save it as a string, but thought there should be a better way. Thanks
