Math commands

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	atan	atan2
ceil	cos	cosh	double	exp
floor	fmod	hypot	int	log10
log	pow	round	sin	sinh
sqrt	tan	tanh

In addition, these math commands are available:

max(TCL)

returns the argument with the highest numeric value

min(TCL)

returns the argument with the lowest numeric value

random(TCL)

returns a pseudo-random positive integer
