To Set the Variables
You can specify the variable by setting the “Mantissa” and “Exponent” (use 10 as the
base). For example, when the mantissa is set to 6.1074 and the exponent is set to 8，
the variable is set to 6.1074×10
8
.
Press Variable to open the variable setting menu. You can set the variables
(Variable1 and Variable2) may be included in the operation expression using the
