bag.math.get_si_prefix(num: float) → Tuple[int, str]

bag.math.float_to_si_string(num: float, precision: int = 6) → str

Converts the given floating point number to a string using SI prefix.

Parameters:

• num (float) – the number to convert.

• precision (int) – number of significant digits, defaults to 6.

Returns:

ans – the string representation of the given number using SI suffix.

Return type:

str

Parameters:

si_str (str) – the string to convert

Returns:

ans – the floating point value of the given string.

Return type:

float

bag.math.gcd(a: int, b: int) → int
