What is float C?
Float is a datatype which is used to represent the floating point numbers. It is a 32-bit IEEE 754 single precision floating point number ( 1-bit for the sign, 8-bit for exponent, 23*-bit for the value. It has 6 decimal digits of precision.

What is the size of float and double in C?
Floating-Point Types
| Type | Storage size | Value range |
|---|---|---|
| float | 4 byte | 1.2E-38 to 3.4E+38 |

| long double | 10 byte | 3.4E-4932 to 1.1E+4932 |
Why float is used in C?
Float is used mostly in graphic libraries because of their extremely high demand for processing power. Because the range is smaller than in the double type, float has been the better choice when dealing with thousands or millions of floating-point numbers because of its speed.
How small can a float be?
If precision is less of a concern than storage, consider using type float for floating-point variables….Range of Floating-Point Types.
