Explain about the Floating point Constants in c language?

A floating point constant is the number that contains either a fraction or decimal part. If an exponent is present its consequence is to shift the location of the decimal point to the right if the exponent is positive or to the left if the exponent is negative and if a decimal point isn't included within the number it is assumed to the positioned to the right of the digit. A real number may as well be expressed in exponential form. For instance the value 237.95 may be written as 23795E2 in exponential notation. E2 mean multiply by 10².
