php - Calculating an Exponent -
in excel =(b5/2)^2*3.141592654, b5 rod.
this doesn't produce same results.
$rodarea = $rod/2 ^2*3.141592654 ; what doing wrong? thanks.
my guess error in whatever language (perl?) written in:
$rodarea = $rod/2 ^2*3.141592654 ;
many programming languages don't honor ^ exponent operator, due ambiguity xor ^. typically have function pow or exp exponents. in case do:
$rodarea = (($rod/2)*($rod/2))*3.141592654 ; (exponent in perl **, not ^, though don't know if that's right language).
