What is float value in Java?
Float is a single-precision value that has a width of 32 bits in storage. On some processors, this single precision is faster and takes less size when compared to the double-precision. This is arguable as on some modern processors, double-precision is faster than the single-precision.Why can 0.1 be represented as a float?
The reason you can't represent 0.1 as a binary floating point number is for exactly the same reason. You can represent 3, and 9, and 27 exactly - but not 1/3, 1/9 or 1/27. The problem is that 3 is a prime number which isn't a factor of 10.What is a float value in Python?
Float is used to represent real numbers and is written with a decimal point dividing the integer and fractional parts. For example, 97.98, 32.3+e18, -32.54e100 all are floating point numbers. Python float values are represented as 64-bit double-precision values.How do you write a float?

How do you enter a float value in Python?
