## Description

These macros provide a portable method to determine the limits of some of the standard integer and floating point types.

## Details

### G_MININT

    #define G_MININT	INT_MIN

The minimum value which can be held in a gint.

### G_MAXINT

    #define G_MAXINT	INT_MAX

The maximum value which can be held in a gint.

### G_MAXUINT

    #define G_MAXUINT	UINT_MAX

The maximum value which can be held in a guint.

### G_MINSHORT

    #define G_MINSHORT	SHRT_MIN

The minimum value which can be held in a gshort.

### G_MAXSHORT

    #define G_MAXSHORT	SHRT_MAX

The maximum value which can be held in a gshort.

### G_MAXUSHORT

    #define G_MAXUSHORT	USHRT_MAX

The maximum value which can be held in a gushort.

### G_MINLONG

    #define G_MINLONG	LONG_MIN

### G_MAXLONG

    #define G_MAXLONG	LONG_MAX

The maximum value which can be held in a glong.

### G_MAXULONG

    #define G_MAXULONG	ULONG_MAX

### G_MININT64

    #define G_MININT64	((gint64)  0x8000000000000000)

The minimum value which can be held in a gint64.

### G_MAXINT64

    #define G_MAXINT64	((gint64)  0x7fffffffffffffff)

The maximum value which can be held in a gint64.

### G_MAXUINT64

    #define G_MAXUINT64	((guint64) 0xffffffffffffffff)

The maximum value which can be held in a guint64.

    #define G_MINFLOAT	FLT_MIN

The minimum value which can be held in a gfloat.

### G_MAXFLOAT

    #define G_MAXFLOAT	FLT_MAX

The maximum value which can be held in a gfloat.

### G_MINDOUBLE

    #define G_MINDOUBLE	DBL_MIN

The minimum value which can be held in a gdouble.

### G_MAXDOUBLE

    #define G_MAXDOUBLE	DBL_MAX

The maximum value which can be held in a gdouble.
