What are 2 decimal places?
“Two decimal places” is the same as “the nearest hundredth”.
So, for example, if you are asked to round 3.264 to two decimal places it means the same as if your are asked to round 3.264 to the nearest hundredth.
Some questions, like the example below, will ask you to “show your answer correct to two decimal places.”.
Who invented 0 in India?
AryabhataWhat is widely found in textbooks in India is that a mathematician and astronomer, Aryabhata, in the 5th century used zero as a placeholder and in algorithms for finding square roots and cube roots in his Sanskrit treatises.
Is zero a decimal number?
The concept of zero as a written digit in the decimal place value notation was developed in India, presumably as early as during the Gupta period (c. 5th century), with the oldest unambiguous evidence dating to the 7th century.
How do you read decimals with zeros?
For instance, a decimal number such as: 0.005 is read as “zero point zero, zero, five” and 4.2 is read as “four, point two.” 578 is written and read as twenty-five, point five seven eight. 14 is written and read as seven thousand, point one four. 002 is written and read as zero point zero, zero two.
Is 0.5 rounded up or down?
If the decimal portion is less than 0.5, we round down, if the decimal portion is more than 0.5, we round up, and if the decimal portion is exactly 0.5, we look at the place value to the left of the five (yes, really, the left!). If it’s an odd number, you round up, and if it’s an even number, you round down.
Who invented the 0?
MayansThe first recorded zero appeared in Mesopotamia around 3 B.C. The Mayans invented it independently circa 4 A.D. It was later devised in India in the mid-fifth century, spread to Cambodia near the end of the seventh century, and into China and the Islamic countries at the end of the eighth.
Who invented 1?
Hindu-Arabic numerals, set of 10 symbols—1, 2, 3, 4, 5, 6, 7, 8, 9, 0—that represent numbers in the decimal number system. They originated in India in the 6th or 7th century and were introduced to Europe through the writings of Middle Eastern mathematicians, especially al-Khwarizmi and al-Kindi, about the 12th century.
What is 1/3 as a decimal rounded to 2 decimal places?
I ideally believe in significant figures, so I would rather write it down as 0.3 . Most people will write it down as 0.33,0.333,0.3333 , etc. In practice use 13 as 0.333 or 0.33 , depending on the level of accuracy required.
How do you find decimal places?
The first digit after the decimal represents the tenths place. The next digit after the decimal represents the hundredths place. The remaining digits continue to fill in the place values until there are no digits left.
What is 0.05 rounded to the nearest whole number?
The decimal 0.05 rounded to the nearest whole number is 0.
How do you round to zero decimal places?
Tip on Rounding Decimals When you round, everything to the right of the given place value becomes a zero, and the digit in the given place value either stays the same or rounds up one. Trailing zeros after the decimal point should be dropped. Round 10.473 to the nearest tenth.
What is the result of round 0.5 round (- 0.5 in Python?
In the above output, you can see that the round() functions on 0.5 and -0.5 are moving towards 0 and hence “round(0.5) – (round(-0.5)) = 0 – 0 = 0“.
Why do we round up from 5?
The tie-breaking rule means that “more” round up than down. Because everyone prefers even numbers. Rounding 5 up means that as many numbers are rounded up as are rounded down. If you consider single-digit numbers, then 0, 1, 2, 3, 4 are rounded down, and 5, 6, 7, 8 and 9 are rounded up.
