Appendix A. CRBasic Programming Instructions Round Rounds a value to a higher or lower number. Syntax variable = Round (Number, Decimal) SGN Finds the sign value of a number. Syntax x = SGN(source) Sqr Returns the square root of a number. Syntax x = SQR(number) A.6.8 Integrated Processing DewPoint Calculates dew point temperature from dry bulb and relative humidity. Syntax DewPoint(Dest, Temp, RH) PRT Calculates temperature from the resistance of an RTD. This instruction has been superseded by PRTCalc() in most applications. Syntax PRT(Dest, Reps, Source, Mult) PRTCalc Calculates temperature from the resistance of an RTD according to a range of alternative standards, including IEC. Syntax PRTCalc(Dest, Reps, Source, PRTType, Mult, Offset) SolarPosition Calculates solar position Syntax SolarPosition(Dest, Time, UTC_OFFSET, Lat_c, Lon_c, Alt_c, Pressure, AirTemp) SatVP Calculates saturation‐vapor pressure (kPa) from temperature. Syntax SatVP(Dest, Temp) StrainCalc Converts the output of a bridge‐measurement instruction to microstrain. Syntax StrainCalc(Dest, Reps, Source, BrZero, BrConfig, GF, v) 477
