@gururaj1512 In the C standard library, the FLT_MIN_10_EXP macro for the minimum base 10 exponent for a normal single-precision floating-point number is defined as -37.
While the smallest positive normal single-precision floating-point number has a base 10 exponent of -38 (~1.17549435e-38), standard libraries define the minimum base 10 exponent as -37 to ensure that any number greater than or equal to 10^{-37} is representable as a normal float. We should use this value instead, as it is the widely accepted and used one in various programming languages.
