evalhf/constant

constants known to evalhf

Description

 • The following constants are known to evalhf:

 Pi gamma Catalan true false FLT_RADIX DBL_MANT_DIG DBL_DIG DBL_EPSILON DBL_MIN_EXP DBL_MIN DBL_MIN_10_EXP DBL_MAX_EXP DBL_MAX DBL_MAX_10_EXP LNMAXFLOAT

 • evalhf(Digits) returns the approximate number of digits of the hardware floating-point system in use, regardless of the actual setting of Digits. This constant takes into account the precision returned by the standard mathematical functions.
 • Inside evalhf, true has the value 1.0 and false has the value 0.0.
 • The following constants are taken from the ANSI-C definition of floating-point parameters of an IEEE-standard floating-point system.
 • DBL_EPSILON: The smallest positive x such that $1.0+x\ne 1.0$
