Deborah.Sarah.AvgErrFormatter

avgerr_e2d(
    censtr::String, 
    errstr::String
) -> String

Format a central value and its error into a compact string using parenthetical $\pm$ notation.

This function takes the central value and error as strings in scientific notation (e.g., "1.234e+01", "3.2e-01"), and returns a formatted string such as "12.3(3)". It handles different scales and adds a * suffix if the error dominates.

Arguments

• censtr::String : Central value string in scientific notation.
• errstr::String : Error value string in scientific notation.

Returns

• String : Formatted result like "1.23(45)" or "1.2(3) *" depending on magnitude and dominance.

avgerr_e2d_from_float(
    cen::Float64, 
    err::Float64
) -> String

Convert a central value and its error from Float64 into a compact exponential $\pm$ string.

This is a wrapper for avgerr_e2d that takes float inputs and internally converts them to scientific notation strings with high precision before formatting.

Arguments

• cen::Float64 : Central value.
• err::Float64 : Error value.

Returns

• String : Formatted output like "1.23(4)e+02" or "1.2(3) *".

round_sig(
    x::Float64, 
    sig::Int=2
) -> Float64

Round a number to a specified number of significant digits.

Arguments

• x::Float64 : Number to round.
• sig::Int=2 : Number of significant digits (default: 2).

Returns

• Float64 : The number rounded to the specified significant digits.
