log10x=21

how do you work this out ?


thanks.

log₁₀x = 21, means that 10²¹ = x, so x = 1,000,000,000,000,000,000,000: one billion million million.

ahh - sort of like 2^3 = 8

cheers.

Oh wow, I too fiddle around with ports in VB for my TI. You see, I wanted to make a VB based application that allowed basic programmers to execute any wav/midi from the computer thru simple TI-basic command(s). To do this, it needs valid connection between your calc and your computer. Then use simple commands like Send() to execute various sounds.

My program allowed up to 200 different wav sounds and 20 different midi's. To function this, you need to download/get a wav or midi file. You assign what number they are going to be . For example, using my VB application, you assign Sound #1 as Laugh.wav. Then assign Midi music #1 as Theme01.mid and so on. So in order to execute this you need this on your calculator

:Clrhome
:Send(1 'Execute soundFX #1
:Send(201 'Execute MidiMusic #1
:Stop

You get it? For awhile it worked great. Using this VB application I've made, I was able to have computer wav/midi music during the opertion of the game. Unfortunately, my tester revealed that this didn't work. That's where I need help. I know that when you use a command "Send(1)", it sends weird variable to the PC. And that variable is read gibberish. So how do I receive a variable to the computer and transulate that gibberish to more readable format... like HEX or something.
