Cbabel 0 Posted March 7, 2007 Report Share Posted March 7, 2007 Hello to everybody, I have bought the Source Boost Compiler to work with the MPLAB from Microchip. For a project I need some Math functions, espezially the expontential funktion and the common logarithm. Now I read the Boost.c description and I only found some arthmetic function like + - / ..... Now I'm searching for Libraries who integrate this Math functions. Are there libraries at all who contains these functions? Thanks Chris Quote Link to post Share on other sites

I did not know the Boost BASIC was for sale yet? But I will see if I can help you. Quote Link to post Share on other sites

These are the formulas for the calculation. description: r = relative humidity T = Temperature in °C TD = Dewpoint Temperature in °C DD = Vapor Pressure in hPa SDD = Saturation Vapor Pressure in hPa Parameter: a = 7.5, b = 237.3 für T >= 0 Formula: SDD = 6.1078 * 10^((a*T)/(b+T)) DD = r/100 * SDD TD = (234,67*(log10(DD)- 184,2))/(8,233- log10(DD)) Can you help me?
