Math commands (TCLX)
Several extended math commands add functionality
in TclX. In addition, a set of procedures provide
command access to the math functions supported by the expr command.
The following procedures provide command interfaces to the expr math
functions. They take the same arguments as the expr functions and
may take expressions as arguments.
abs acos asin atan2
atan ceil cos cosh
double exp floor fmod
hypot int log10 log
pow round sin sinh
sqrt tan tanh
