Jan 14, 2017 · In your example the string "1e+11" means the number $1 \cdot 10^{+11} = 10^{11} = 1\underbrace{00000000000}_{11 \, "0" \mbox{symbols}}$ Note that the resulting number is given by a string as well, just a usually more familiar one, the base 10 positional system representation learned in school.

Apr 18, 2019 · In particular, I've never seen "1e" convention before. As others have mentioned, practically speaking, 1e6 is scientific notation for 10^6 which is 1000000 or better known as 1 million. But as has already been mentioned, by David, this is actually treated as a double in C and the value is actually 1000000.0 .

I have seen in some codes that people define a variable and assign values like 1e-8 or 1e5. for example const int MAXN = 1e5 + 123; What are these numbers? I couldn't find any thing on the web...

Apr 5, 2017 · Hello I came across a math equation and I was wondering what did the "e" stand for? the equation is : y=47931x-1E+0.8 Can someone please help me by showing what the E stands for and the answer for my equation. I know that I need to sub in a point for x so the only thing stopping me from answering the question is what to do for the 1E+0.8 part.

1e-5 = 1 × 10 −5 = 0.00001 (the number you gave) 0.369E+2 = 0.369 × 10 2 = 36.9 (another example) In ...

1e-9 is 0.000000001; the minus sign applies to the exponent.-1e9 is -1000000000.0; the minus sign applies to the number itself. The e (or E) is the so called exponential notation and it means "times 10-to-the-power-of", so 1e9 is "one times ten to the ninth power", and 1e-9 means "one times ten to the negative ninth power".

Aug 25, 2016 · math.e or from math import e (= 2.718281…). The two expressions math.exp(x) and e**x are equivalent however: Return e raised to the power x, where e = 2.718281… is the base of natural logarithms.

Aug 13, 2022 · The approach with this +1e-7, as I showed above, is too easy to fail. No, don't use it, no, never. There are lots of proper libraries for fixed-point arithmetic, just pick one and use.

Nov 7, 2016 · How to understand this number with "double scientific"-notation (~1e-9-4.999e-1) in matplotlib 1 What does a string like 1e-6+6.0459e-1 mean in the context of a vertical axis label in a matplotlib plot?

Dec 19, 2014 · How to convert 1e+30 to 1000000000000000000000000000000 I want number as it is entered by User do not convert like 1e+30.
