Description
Returns the fractional (decimal) part of a float by computing A - floor(A). For example, 3.7 returns 0.7.
Caveats & Gotchas
- • For negative inputs the result is non-negative: Fraction(-1.7) returns 0.3, because floor(-1.7) == -2. This differs from simple truncation (frac of -1.7 via truncation would be -0.7).
- • Not suitable as a substitute for Percent_FloatFloat when you need the remainder relative to an arbitrary divisor — Fraction is always relative to 1.0.
