Adding or Subtracting Decimals
Write the issue vertically & line up the decimal points. Add any necessary zeroes to the right side of any numbers in order to make the numbers the same length.
Multiplying Decimals
Drop the decimal points & multiply normally (as you would multiply whole numbers). At the finish, count the total number of digits to the right of the decimal in the original numbers. Insert the same number of decimal places in to the answer.
Terminating Decimals
Decimals that terminate, or finish, at some point; decimals that do not go on forever. 16.9is a terminating decimal. 16.9does not terminate. ; also does not terminate.
SO welcome to decimal home !
Decimal data type Decimal variables are stored as 96-bit (12 byte) unsigned integer form, and divided by the number of a power of 10. The variable scale factor determines the right number of
decimal digits, ranging from 0-28.
Variable scale factor is 0 (no decimal places) of the case, the maximum possible value is + / -79,228,162,514,264,337,593,543,950,335. In the 28 decimal places, the maximum value is + / -7.9228162514264337593543950335, while the smallest non-zero value is + / -0.0000000000000000000000000001. Note At this point, Decimal data type can only be used in Variant, that is, can not declare a variable of type Decimal. But can Cdec function, create a sub-type to Decimal in the Variant. This right.
Decimal data type can be used in powerBuilder. Directly in the preparation of control when using on it. For example: When writing a Clicked event script so you can use decimal r. decimal [(p [, s])] and numeric [(p [, s])] fixed effective number of digits and decimal places.
When using the maximum effective number of bits, the valid values is from – 10 ^ 38 +1 to 10 ^ 38 – 1. decimal in SQL-92 synonym is dec and dec (p, s). numeric functions as decimal. p (effective number of bits) can store the maximum number of decimal digits, decimal point left and right sides are covered. Effective number of bits must be 1 to 38 of the largest value between the median effective. Default is 18 effective bits. s (number of decimal places) the right of the decimal point can store the largest decimal digit. Number of decimal places must be from 0 to p values. Only when the effective number of bits specified in order to specify the number of decimal places.

So. We all know hex decimal is abject 16.
Base 16 is area the ‘numbers’ you can use are aught through to the letter F (i.e. the decimal amount for ‘1′ is represented in hex decimal as ‘1′ but the hexadecimal amount of ‘15′ (decimal) is apparent as ‘F’ (hexadecimal) and the amount of ‘17′ (decimal) is ‘11′ in Hex decimal.
This is hex decimal convert .next we will talk about binary decimal convert .
Today, we will Introduction decimal convert to hex decimal and binary decimal .
First decimal convert to hex decimal .
1998.12=144E.2(hex)=11111001110.0001(binary)
742.25=2E6.4(hex)=10001110110.01(binary)
