gvars in telemetry: Interpret gvars as decimal

Browse source 
The value of GVars is now interpreted as a decimal constant,
with the decimal place determined by the precision of the
calculated telemetry source.

Examples:
Precision 0.0 (aka precision=1)
GVar has value 20
=> calculation uses value 2.0

Precision 0.00 (aka 2)
GVar has value 3
=> calculation uses value 0.03
