How do you convert a floating number to hexadecimal?
Take decimal number as dividend. Divide this number by 16 (16 is base of hexadecimal so divisor here). Store the remainder in an array (it will be: 0 to 15 because of divisor 16, replace 10, 11, 12, 13, 14, 15 by A, B, C, D, E, F respectively). Repeat the above two steps until the number is greater than zero.
How do you convert a decimal to hexadecimal on a calculator?
How to convert from decimal to hex. Divide the decimal by 16 until the result is 15 or less. Take the whole number (before the decimal point) and look up the corresponding hex value in the decimal and hex reference list below (e.g. 10 = A, 15 = F). Take the remainder (after the decimal point) and multiply by 16.

The finite representation of 1/10 is 0.0 0011 ‾ 0.0\overline{0011} 0.00011, but it can’t be represented in floating-point because we can’t deal with bars in floating-point. We can represent it only in fixed digits/bits using any data type.
Can a float hold a decimal?
The float data type has only 6-7 decimal digits of precision. That means the total number of digits, not the number to the right of the decimal point. Unlike other platforms, where you can get more precision by using a double (e.g. up to 15 digits), on the Arduino, double is the same size as float.
