VMS Help RTL Routines, MTH$, MTH$xSQRT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Square Root routine returns the square root of the input
    value floating-point-input-value.

    Format

      MTH$SQRT  floating-point-input-value

      MTH$DSQRT  floating-point-input-value

      MTH$GSQRT  floating-point-input-value

      Each of the above formats accepts one of the floating-point
      types as input.

1 - Corresponding JSB Entry Points

      MTH$SQRT_R3

      MTH$DSQRT_R5

      MTH$GSQRT_R5

      Each of the above JSB entry points accepts one of the floating-
      point types as input.

2 - Returns

    OpenVMS usage:floating_point
    type:         F_floating, D_floating, G_floating
    access:       write only
    mechanism:    by value

    The square root of floating-point-input-value. MTH$SQRT returns
    an F-floating number. MTH$DSQRT returns a D-floating number.
    MTH$GSQRT returns a G-floating number.

3 - Argument

 floating-point-input-value

    OpenVMS usage:floating_point
    type:         F_floating, D_floating, G_floating
    access:       read only
    mechanism:    by reference

    Input value. The floating-point-input-value argument is the
    address of a floating-point number that contains this input
    value. For MTH$SQRT, floating-point-input-value specifies an
    F-floating number. For MTH$DSQRT, floating-point-input-value
    specifies a D-floating number. For MTH$GSQRT, floating-point-
    input-value specifies a G-floating number.
