func CPU ¶

func CPU(s string) (int, error)

CPU parses the string s to see if it contains NumCPU()* (with the star), if so the number behind it (without a space) multiplied with runtime.CPU() and returns, otherwise a number if assumed and that is parsed. A negative number returns an error if seen after `numcpu()*`, but we allow -1 in the normal expression.
