Could anybody explain floating point types numbers concisely, because the books definition I am reading is somewhat confusing, and explain how it is applicable in real life.

an int is a single number (without decimal point- it is an integer ie -2, -1, 0, 1, 2, ...)

float, double, decimal are all forms of a decimal number - not to be confused with decimal data type- (eg: 1.34, 5.68, 8.22, etc) but with varying degrees of precision.

a float has up to 7 points of precision, a double has 15-16 points of precision, and a decimal has 28-29 points of precision. These are data types of .Net, most languages are relatively close by comparison in 'what' the data types are called and their precision and size.

Floating pont is a character which

contains numbers or integers that

is decimal. That is according to our

Computer Science professor. Good day!
