Produce

small Source #

Arguments

:: Int	Coefficient
-> Int	Exponent
-> Scientific

Construct a Scientific from a coefficient and exponent that fit in a machine word.

large Source #

Arguments

:: Integer	Coefficient
-> Integer	Exponent
-> Scientific

Construct a Scientific from a coefficient and exponent of arbitrary size.

fromFixed :: HasResolution e => Fixed e -> Scientific Source #

Construct a Scientific from a fixed-precision number. This does not perform well and is only included for convenience.
