STDMATH Global Constants | ![]() |
*INFINITY* real ~1.7e308 ; pretty large number
*MACHINE-EPSILON* real ~2.22e-16 ; lowest possible epsilon
*MAX-INT* int 2147483647 ; normally *MAX-LONGINT*
*MAX-LONGINT* int 2147483647 ; signed long int (32 bit signed int)
*MAX-SHORTINT* int 32767 ; signed short int (16 bit signed int)
*MAX-REAL* real ~1.7e308 ; double float, 64 bit, 15 digit prec
*PI2* real 6.28319 ; (* PI 2)
*PI/2* real 1.5708 ; (/ PI 2) == 90°
*PI/4* real 0.785398 ; (/ PI 4) == 45°
*NUM-TOL* real 1e-6 ; equalp tolerance
*EPSILON* real 1e-12 ; numeric precision treshold
*MAX-INT* is provided for portability reasons. (panic mode)
*NUM-TOL* is used in STD-EQUALP and may be used by user functions too.
*EPSILON* is used in some library arithmetic algorithms and may be used by user functions too.
