Method getMantissa

qcustomplot.cpp:5816–5821

! \internal Returns the decimal mantissa of \a input. Optionally, if \a magnitude is not set to zero, it also returns the magnitude of \a input as a power of 10. For example, an input of 142.6 will return a mantissa of 1.426 and a magnitude of 100. */

  For example, an input of 142.6 will return a mantissa of 1.426 and a magnitude of 100.
