Math::Cephes Description

Math::Cephes is a Perl interface to the cephes math library. Math::Cephes is a Perl interface to the cephes math library.SYNOPSIS use Math::Cephes qw(:all); This module provides an interface to over 150 functions of the cephes math library of Stephen Moshier. No functions are exported by default, but rather must be imported explicitly, as in use Math::Cephes qw(sin cos); There are a number of export tags defined which allow importing groups of functions:use Math::Cephes qw(:constants); imports the variables $PI : 3.14159265358979323846 # pi $PIO2 : 1.57079632679489661923 # pi/2 $PIO4 : 0.785398163397448309616 # pi/4 $SQRT2 : 1.41421356237309504880 # sqrt(2) $SQRTH : 0.707106781186547524401 # sqrt(2)/2 $LOG2E : 1.4426950408889634073599 # 1/log(2) $SQ2OPI : 0.79788456080286535587989 # sqrt( 2/pi ) $LOGE2 : 0.693147180559945309417 # log(2) $LOGSQ2 : 0.346573590279972654709 # log(2)/2 $THPIO4 : 2.35619449019234492885 # 3*pi/4 $TWOOPI : 0.636619772367581343075535 # 2/pi As well, there are 4 machine-specific numbers available: $MACHEP : machine roundoff error $MAXLOG : maximum log on the machine $MINLOG : minimum log on the machine $MAXNUM : largest number representeduse Math::Cephes qw(:trigs);
