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 available commands are "Print in scientific notation (%e/%E)" and "Automatically print in scientific notation if the number is very long (%g)". No options seem to be available to print the number in its normal form. I realize that I could write a function that

We have a StreamBuffer class in which we haven't implemented std::fixed operations and I am trying to prevent number showing up in scientific notations. With my below code some numbers are getting shown in scientific notations. We want to avoid doing any allocations so that's why we implemented StreamBuffer class because of performance reason. Below is the code: T value = 0; template<typename U> void process(U& buf, DataOption holder) const { if (holder == DataOption::TYPES) { switch (type_) { case teck::PROC_FLOAT: buf << "{\"float\":" << value << "}"; break; case teck::PROC_DOUBLE: buf << "{

I need to get the value of an extremely large number in JavaScript in non-exponential form. Number.toFixed simply returns it in exponential form as a string, which is worse than what I had. This is what Number.toFixed returns: >>> x = 1e+31 1e+31 >>> x.toFixed() "1e+31" Number.toPrecision also does not work: >>> x = 1e+31 1e+31 >>> x.toPrecision( 21 ) "9.99999999999999963590e+30" What I would like is: >>> x = 1e+31 1e+31 >>> x.toNotExponential() "10000000000000000000000000000000" I could write my own parser but I would rather use a native JS method if one exists.

I'm making a function to return the number of decimal and whole number digits and am converting the inserted typename number to a string using sstream s. However the number when being converted to a string comes out in scientific notations which is not useful for counting the number of digits are in the normal number. How can I stop this from happening in my function below? enum { DECIMALS = 10, WHOLE_NUMBS = 20, ALL = 30 }; template < typename T > int Numbs_Digits(T numb, int scope) { stringstream ss(stringstream::in | stringstream::out); stringstream ss2(stringstream::in | stringstream::out)

I am trying to put a colorbar to my image using matplotlib. The issue comes when I try to force the ticklabels to be written in scientific notation. How can I force the scientific notation (ie, 1x10^0, 2x10^0, ..., 1x10^2, and so on) in the ticks of the color bar? Example, let's create and plot and image with its color bar: import matplotlib as plot import numpy as np img = np.random.randn(300,300) myplot = plt.imshow(img) plt.colorbar(myplot) plt.show() When I do this, I get the following image: However, I would like to see the ticklabels in scientific notation... Is there any one line

Consider the following Python snippet: for ix in [0.02, 0.2, 2, 20, 200, 2000]: iss=str(ix) + "e9" isf=float(iss) print(iss + "\t=> " + ("%04.03e" % isf ) + " (" + str(isf) + ")") It generates the following output: 0.02e9 => 2.000e+07 (20000000.0) 0.2e9 => 2.000e+08 (200000000.0) 2e9 => 2.000e+09 (2000000000.0) 20e9 => 2.000e+10 (20000000000.0) 200e9 => 2.000e+11 (2e+11) 2000e9 => 2.000e+12 (2e+12) My question is - is it possible to "go back" somehow? That is: 2.000e+07 => 0.02e9 2.000e+08 => 0.2e9 2.000e+09 => 2e9 2.000e+10 => 20e9 2.000e+11 => 200e9 2.000e+12 => 2000e9 ... I'd specify I want

I want to make a function that takes an entered value and converts it to scientific notation (N x 10^a) I've tried many different things, but I can't seem to get it right. Example: I enter 200. The converter converts it to 2 x 10^2 You can do something like this: a = 200 a.toExponential(); //output 2e+2 fiddle: http://jsfiddle.net/Q8avJ/9/ At some point I wanted to use the coefficient and the exponent as numbers. If you want to do that, you can use toExponential function, split the string and convert the items of the array to numbers. In the following snippet I assign the numbers to the
