.SH NAME
WyMath \- namespace of float point number functions
.SH SYNOPSIS
.PP
.B #include <wymath.h>
.PP
 namespace \fBWyMath\fP {
   double \fB_scif\fP(double,double&)
 };
.SH "DESCRIPTION" 
.\"--------------------------------------------
.PP
.BI "double _scif(double " "x" ", double& " "p10" ")"
.PP
    Decompose \fIx\fP into product of two numbers in the form:
    \fIx\fP=\fBfr\fP*10^\fIp10\fP, \fIp10\fP is reset with the exponent which is a whole
    number. And then, the mantissa \fBfr\fP (1.0<= abs(\fBfr\fP) <10.0, or 0
    iff \fIx\fP is 0) is returned.

    Note: Error ratio of tested samples is less than 1e-13
.PP 
    [\fBRet\fP] Mantissa of the decomposition
