What is the precision of float in 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.

How do you print float up to 2 decimal places?

Call str. format(number) with “{:. 2f}” as str and a float as number to return a string representation of the number with two decimal places. Call print(string) with the formatted float-string as string to print the float.
