DBL_MIN_10_EXP Macro

Minimum negative integer value for a double precision floating-point exponent in base 10.

Include

<float.h>

Value

The value -37 by default; -307 if the switch -fno-short-double is used.

Remarks

By default, a double type is the same size as a float type (32-bit representation). The -fno-short-double switch allows the IEEE 64-bit representation to be used for a double precision floating-point value.
