In Excel it is the "code" function.
For example, Code("A") = 65
0.999 repeating = 1 (the integer).
No, if it has a decimal place then its not an integer
To write a number as an integer, you simply express it without any fractional or decimal components. If the number is already a whole number, you can write it as is. For decimal numbers, round to the nearest whole number or truncate any decimal portion to convert it into an integer. For example, 4.7 becomes 5 (when rounded) or 4 (when truncated).
an integer won't have any decimal point
You cannot. A mixed number, by definition, has a fractional part. In converting to a decimal number, you cannot get rid of that fractional part and so you can never convert it to a decimal integer.
The INT function is to convert something into an integer. An integer is a number that goes out two decimal places.
0.999 repeating = 1 (the integer).
18 (eighteen) is an integer and does not need to be "converted to a decimal"1/8 (one eighth) is a fraction and can be converted into a decimal: 0.125
The integer part of the mixed number is the integer part of the decimal. The use long division to convert the fractional part of the mixed number to the fractional part of the decimal.
To convert 40.5% to decimal divide by 100: 40.5% ÷ 100 = 0.405
110 is an integer: there is not a sensible way to convert it to a fraction.
A decimal number is not an integer. An integer is a number that is not a fraction, and decimal numbers are decimal fractions.
38 is an integer, it does not need to be converted. 3/8 is a fraction, it is equal to 0.375
4111 is an integer and so there is no sensible way to convert it into a repeating decimal.
No, if it has a decimal place then its not an integer
No by definition a decimal number can never be an integer because an integer is a whole number (it can not have any decimal parts).
