abs(b1) |
ABS(b1) implements the Absolute Value function: the result is to drop the negative sign (if present). |
ABS(7) = 7. |
|
exp(x) |
EXP(x) computes the value of e (the base of natural logarithms) raised to the power of x (exp(x) means the exponential function of x, i.e. ex.). |
EXP(2) = 7.389056. |
|
inch(x) |
INCH(x) converts millimeters to inches. inch(x) computes the number of inches equivalent to x millimeters. |
INCH(25.4) = 1. |
|
log10(x) |
LOG10(x) computes the base-10 logarithm of x. |
LOG10(7) = 0.845098. |
|

|
sinh(x) |
SINH(x) returns the hyperbolic sine of x, which is defined mathematically as (ex−e−x)/2. x is in radians. |
SINH(0.5) = 0.521095. |
|
cosh(x) |
COSH(x) returns the hyperbolic cosine of x, which is defined mathematically as (ex+e−x)/2. x is in radians. |
