9.4 Numerical Formats
Four numerical formats are supported by CRBASIC. Most common is the use
of base 10 numbers. Scientific notation, binary, and hexadecimal formats may
also be used, as shown in TABLE 9.4-1. Only standard base 10 notation is
sup
ported by Campbell Scientific hardware and software displays.
TABLE 9.4-1. Formats for Entering Numbers in CRBASIC
Format Example Value
Standard 6.832 6.832
Scientific notation 5.67E-8 5.67X10
-8
Binary: &B1101 13
Hexadecimal &HFF 255
Binary format is useful when loading the status (1 = high, 0 = low) of multiple
flags or ports into a single variable, e.g., storing the binary number
&B11100000 preserves the status of flags 8 through 1. In this case, flags 1 - 5
are low, 6 - 8 are high. Program Code EXAMPLE 9.4-1 shows an algorithm
t
hat loads binary status of flags into a LONG integer variable.

If Flag(I) = true then
FlagInt = FlagInt + 2^(I-1)
