**float to integer convertion**I have this functions, c3 and c2 that computes and return a float
number. The problem is that wen I pass the result of c2 (float number)
to c3(), in function apears to be an integer. Ex.:
$calc2=c2(params); (float number)
$calc3=c3($calc2); ($calc2 - float number)
echo $calc3; (is not the number that supposed to be, because c4
computes $calc2 as if it were an integer: if $calc=39.96 it wil be
converted in 39).
What is the problem? I really can't see it.

function c2($j,$n)
{
//=(J54*100)/N47
$c=$j*100/$n;
return number_format($c,2,",",".");

**integer to floating poit converter**Hi all.
I want to have an integer to floating point converter. On the other
hand I want a floating point generator to convert some numbers from
integer to floating point . so I can use them as elements of the
"primitive table" in verilog code. Have any one help me ? how I can
get such tools? I also want to implement the 16 bit floating point
adder and multiplier in ASIC. So I must know the operation of them.
Please help me. Thanks.
Regards, mehr.

**Converting Integer / Float to String**Hi List,
is there another way to convert a given String to an Integer or Float type?
I am currently using some code like this:
begin
Value :=Float'Value(Float_String);
exception
when Constraint_Error => Value := 0.0;
end;
For me this is very ugly and a big hack.
Thanks for any idea.
Greetings
Alexander
Another way is to use the "Ada.Float_Text_IO" package. Especially when
you may normally need the Float_Text_IO package in the program.
Read a integer from a string (buffer) using the "Get" routine:
procedure Get ( From : in String ;

**Rounding error when doing float-to-integer**
Im getting a rounding error when doing a floating-point to integer
conversionen. 1.998 is converted to 2, while 1.997 - 1.000 is converted
to 1. So it uses tozero rounding for everything except .998
x = y * APRAMETER
the value of APARAMETER is 0.002
Im using a SUN Ultra 1 creator 3D with Solaris and Fortran 77 SC 4.2
The same conversion on the same machine but in C using CC gives the
correct results (rounding tozero).
Anyone else that has experienced this?

**Converting a string to integer/float**Hello,
I am stuck with a problem, might be very trivial, to ask here, but

my use ?

**Problems converting Float to Integer efficiently**Hi all!
I have been having problems getting decent code out of GNAT 3.15p (Intel architecture)
All I want to do is get the integer part of a Float variable (without checks).
I don't want rounding to nearest like I get with "Integer (Y)"
In C, a function to do this might look like:
int x (float y) { return y; }
Which generates code like:
pushl %ebp
movl %esp,%ebp
subl $12,%esp
flds 8(%ebp)
fnstcw -4(%ebp)
movl -4(%ebp),%edx
movb $12,%dh
movl %edx,-12(%ebp)
fldcw -12(%ebp)
fistpl -12(%ebp)

Google says:
Your search - float2rawInt - did not match any documents.
Are you sure about that function? What's a sortable integer?

**Dividing integers...Convert to float first?**I'm still pretty new to Python. I'm writing a function that accepts
thre integers as arguments. I need to divide the first integer by te
second integer, and get a float as a result. I don't want the caller of
the function to have to pass floats instead of integers. How do I
convert the arguments passed to the function into floats before I do
the division? Is this necessary, or is their a better way?
Thanks,

**How to convert a column of integers to float(4.2)??**This is a newbie, and I suspect, a question with a very easy number.
I'm surprised googling wasn't much help.
How do I convert a whole column of of integers to numbers with 4
digits before and 2 digits after a decimal point?
For example, 2091 becomes 20.91 and 124 becomes 1.24 in the table?
Thanks!

**Float.round**I am suggesting to change the Float.round function to use the
well-known round-to-even method in case of a tie, i.e. x.5, where the
distance to ceil and floor is equal.
round currently uses a round-away-from-zero strategy. This strategy
will introduce a bias when applied to many numbers, i.e. the average of
the rounded numbers will be higher than that of original numbers. This
effect does make a considerable difference, despite the singular nature
of the x.5 values. Consider e.g. the computation of the median of an
array with floats.
Here is a quick hack ruby implementation which adds round ...

**converting uint8 arrays to integers, floats and doubles**Hey Matlab Family:
I've got to process some files FTP'd from a VAX machine. In these
files are various types of data: bytes, short integers, long
integers, floats, and doubles. Parsing the data off by category is
no problem, but interpreting them is. For instance, a page of data
might be formated as follows: double(1), byte(3), short(1), long(1),
byte(5), double(1). And there might be 200000 pages in a file.
I can fread all the raw data from the file, and reshape it to match
the number of pages (columns). Thus, I can parse of this matrix by
rows for each category of data: the first 8...

There's a valid reason to use single precision floating point types.

**Rounding of results in conversion of IEEE floats to integers**
Greetings all,
I am converting some floating point numbers to (signed or unsigned)
integers I am not getting the expected results. It is perhaps the result
of the C libraries/compiler that I am using. I have reproduced the same
results on Intel and AMD processors.
As I understand, floating point conversion should be provided as a
fundamental operation in an IEEE compliant FP implementation.
Furthermore, in conversions the rounding schemes below should apply in
the same way that they are applied to the result of one of the
operations (+,-,*,/).
The code below has been c...

**Converting float to 32bit signed Integer value? (newbie)**Hi there,

fs.close()
However, i need to read a float from this array, but of course, the
following code does not work :
value = float(self.buffer32.pop(0))
e.g instead of getting a value like 2.456 i get 2
How could i properly extract floats from this buffer in phython?
Additionally, how could i store floats into this buffer?

You will need to specify a little more about where these numbers are
