What is 1e9 in Java?
1e9 is simply 10^9. The conversion seems to be from nanoseconds to seconds. –EDIT– Ingo correctly points out that 10e9 is already evaluated by java to a double (see this part of the spec for details).
Is 1e9 an int?
3 Answers. 1e9 is a double that has an exact representation in the IEEE floating point representation. The C++ standard doesn’t mandate IEEE floating point. s is an int , so the double value will be automatically converted to an int .
What does 1e9 mean in a calculator?
1E9 means 1 billion. 1E6 is 1 million.
What is 1E6?
By the way, 1E6 means 1 times 10 to the power 6, which is 1.000. 000, not 100.000. 2E8 means 2 times 10 to the power 8, or 200.000. 000 (two hundred million). It’s simple: 1E6 = 1 followed by 6 zeroes; 2E8 = 2 followed by 8 zeroes.
What is the meaning of 1 E8?
1 E8 m² is used for places that are between 100 km² and 1000 km² in area. The term is based from the scientific notation for 1 x 108m². 100 km² is equal to: 1 E+8 m² a square with sides 10 km long.
What is 1e9 in Python?
-1e9 is -1000000000.0 ; the minus sign applies to the number itself. The e (or E ) means “times 10-to-the”, so 1e9 is “one times ten to the ninth power”, and 1e-9 means “one times ten to the negative ninth power”.
What does 1 E10 mean?
Converting Scientific Notation to a Standard Number E10 means move the decimal to the right 10 places. If the number 1-9 is a whole number, then the decimal may not be seen, but for the purposes of moving the decimal, there is an invisible decimal after each whole number.
Is 1e9 a billion?
To Americans and the French, a billion means a thousand millions (1,000,000,000, or 10 to the ninth, what some British call a milliard, a term that seems never to have been widely accepted).
How do you write 1e6 in Python?
To write a float literal in E notation, type a number followed by the letter e and then another number. Python takes the number to the left of the e and multiplies it by 10 raised to the power of the number after the e . So 1e6 is equivalent to 1×10⁶.
Is 1e6 the same as 10 6?
As others have mentioned, practically speaking, 1e6 is scientific notation for 10^6 which is 1000000 or better known as 1 million.
What is 1e 6 written out?
Scientific notation and metric affixes
| To enter this number | Use this metric affix | Use this E Notation |
|---|---|---|
| 0.000001 | 1u (micro) | 1e-6 |
| 0.000000001 | 1n (nano) | 1e-9 |
| 0.000000000001 | 1p (pico) | 1e-12 |

What is the meaning of -1e9?
-1e9 is -1000000000.0; the minus sign applies to the number itself. The e (or E) means “times 10-to-the”, so 1e9 is “one times ten to the ninth power”, and 1e-9 means “one times ten to the negative ninth power”. In mathematical scientific notation, this is usually denoted by a superscript: 1 × 10 -9 or -1 × 10 9.
What is 1E9 to the 9th power?
The e (or E) means “times 10-to-the”, so 1e9 is “one times ten to the ninth power”, and 1e-9 means “one times ten to the negative ninth power”.
Why is 1E9 different from 1E-9 in binary?
But in the binary representation, the exponent is base 2. So 1e9 and 1e-9 are likely going to be represented very differently. This can lead to discrepancies like you’re seeing. Sep 23, 2014 at 3:08pm UTC
What is the base 10 of 1e9 in C++?
Disch(13742) In C++ the ‘e’ number is base 10. But in the binary representation, the exponent is base 2. So 1e9 and 1e-9 are likely going to be represented very differently. This can lead to discrepancies like you’re seeing.
