Negative numbers: Real numbers that are less than zero. Because zero itself has no sign, neither the positive numbers nor the negative numbers include zero. When zero is a possibility, the following terms are often used: Non-negative numbers: Real numbers that are greater than or equal to zero. Thus a non-negative number is either zero or positive.
It is used in phrases such as cant a mil o bethau i'w wneud "a hundred and one things to do" i.e. "many, many things to do". The number 10,000 is used to express an even larger approximate number, as in Hebrew רבבה r e vâvâh, [36] rendered into Greek as μυριάδες, and to English myriad. [37]
On 2 February 2009, the RBZ announced that a further 12 zeros were to be taken off the currency, with 1,000,000,000,000 third Zimbabwean dollars being exchanged for 1 new fourth dollar. [ 30 ] [ 31 ] New banknotes were introduced with face values of Z$1 , Z$5 , Z$10 , Z$20 , Z$50 , Z$100 and Z$500 . [ 32 ]
The name of a number 10 3n+3, where n is greater than or equal to 1000, is formed by concatenating the names of the numbers of the form 10 3m+3, where m represents each group of comma-separated digits of n, with each but the last "-illion" trimmed to "-illi-", or, in the case of m = 0, either "-nilli-" or "-nillion".

A googol is the large number 10 100 or ten to the power of one hundred. In decimal notation, it is written as the digit 1 followed by one hundred zeros: 10, 000, 000 ...
The decimal expansion of non-negative real number x will end in zeros (or in nines) if, and only if, x is a rational number whose denominator is of the form 2 n 5 m, ...
So too are the thousands, with the number of thousands followed by the word "thousand". The number one thousand may be written 1 000 or 1000 or 1,000; larger numbers are written for example 10 000 or 10,000 for ease of reading.
6.5 × 10 −4966 is approximately equal to the smallest non-zero value that can be represented by a quadruple-precision IEEE floating-point value. 3.6 × 10 −4951 is approximately equal to the smallest non-zero value that can be represented by an 80-bit x86 double-extended IEEE floating-point value.
