Exponential to Float (Getting ALL decimal numbers of Float)
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I need to get ALL decimal numbers possible, but I have a limit of 19 number char on the spinbox. Setting a static numbers on how many decimal places will be and setting a static number of decimals (setDecimals()) is not acceptable since the value I am getting is dynamic.
For example, I want to convert Hertz:
Hertz: 1.00
Megahertz: 1e-6
GigaHertz: 1e-9
I want it to be in this format:
1.00,
0.000006,
0.000000009,
Yes! Decimal places are dynamic.
This is the code for conversion (Value of dictionary is not yet finished):
conversion_formula = {'Hz': 1, 'kHz': 1e-3, 'MHz': 1e-6, 'GHz': 1e-9,
's': 1, 'ms': 1e-3, 'us': 1e-6, 'ns': 1e-9,
'V': 1, 'mV': 1e-3}
if FREQUENCY_UNIT_NAME == title or AMPLITUDE_UNIT_NAME == title:
output_value = input_value * (conversion_formula[current_unit] / conversion_formula[base_unit])
elif title == TIME_UNIT_NAME:
output_value = input_value * (conversion_formula[base_unit] / conversion_formula[current_unit])

1e-9 and 0.000000009 are the same number, just written in a different way. Are you asking how toprintin one format or the other?

in 0.000000009 format. Because when I print the number, it's in 1e-9

All decimal places? Really? What if the value is e.g. π, or even something simpler, like 1/3?
